## Direct Buyer Questions & Instant Calculators (/answers/)
- All 16 Eyewear Questions & Calculators Hub: https://michaeloptical.com/answers/
- How much do prescription glasses actually cost online (without hidden fees)? A complete pair of 1.56 single-vision prescription glasses with standard green anti-reflective and scratch-resistant coatings starts at US$26.90 before shipping (US$16.90 Everyday Picks frame + US$10 lenses, or US$31.90 delivered across the 48 contiguous US states and DC), with US$0 astigmatism surcharge down to -6.00 D. URL: https://michaeloptical.com/answers/prescription-glasses-cost-calculator/
- Can I buy glasses online with high astigmatism (-2.25 to -6.00 CYL) with no extra fee? Yes. MICHAEL Optical supports astigmatism cylinder (CYL) corrections down to -6.00 D on Standard Clear, Blue-Light Filtering and Colored Sun packages (and down to -8.00 D on 1.74 Advanced All-Day Progressives) at US$0 extra cylinder fee, provided you enter an exact Axis between 1° and 180° and an accurate Dual PD. URL: https://michaeloptical.com/answers/high-astigmatism-glasses-no-extra-fee/
- Do I need 1.61, 1.67, or 1.74 high-index lenses for my prescription? For prescriptions within ±3.00 D, 1.56 (US$10/pair) or 1.61 (US$15/pair) is already slim; between ±4.00 D and ±6.50 D, 1.67 Thin High-Index (US$55/pair Single Vision) delivers the best thickness-to-price value; upgrade to 1.74 Ultra High-Index (US$100/pair Single Vision) when your power exceeds ±6.50 D (supported down to -20.00 / +16.00 D), and pair strong powers with a 40–44 mm frame. URL: https://michaeloptical.com/answers/1-67-vs-1-74-high-index-lens-calculator/
- Can you buy progressive glasses online under $100 without getting dizzy? Yes. Pairing any US$16.90 Everyday Picks or SSBC-T frame with US$60 1.56 Clear Progressive lenses brings a complete no-line multifocal pair to US$76.90 before shipping (US$81.90 delivered), with Standard, Upgrade, Advanced and Office corridor tiers all included at US$0 tier surcharge; to avoid swim or dizziness, enter Dual monocular PD and choose a full-rim frame with sufficient vertical lens height. URL: https://michaeloptical.com/answers/progressive-glasses-online-under-100/
- How do I convert Single PD to Dual PD if my doctor didn't write it down? Divide a Single binocular PD (50.0–80.0 mm) by 2 to get symmetrical right and left values for mild single-vision prescriptions (for example, 63 mm equals 31.5 mm OD and 31.5 mm OS); if your prescription exceeds ±4.00 D, includes high astigmatism, or uses progressive multifocal lenses, request or measure separate Dual monocular PD numbers (17.5–41.0 mm per eye) instead of dividing. URL: https://michaeloptical.com/answers/single-to-dual-pd-converter/
- What do the 3 numbers inside my glasses mean (e.g. 49-22-145), and which frames fit me? The three numbers stamped inside your temple arm represent Lens Width × Bridge Width × Temple Length in millimetres (for example, 49-22-145 means 49 mm lenses, a 22 mm nose bridge and 145 mm arms); stay within ±2 mm on lens width and ±1–2 mm on bridge width of a comfortable pair you already wear, and pick 40–44 mm lens widths for narrow faces or strong prescriptions. URL: https://michaeloptical.com/answers/glasses-frame-size-numbers-matcher/
- What lenses reduce night driving headlight glare: polarized, photochromic, or driving lenses? Never wear dark polarized sunglasses at night, and note that standard UV photochromic lenses stay mostly clear inside a car because windshields block UV light; choose high-transmission Day & Night Driving Lenses (all-inclusive US$32 in 1.50, US$36 in 1.61, or US$39 in 1.67 for both Single Vision and Progressive) for night headlight glare, and Polarized Sunglasses (from US$45) for bright daytime highways. URL: https://michaeloptical.com/answers/night-driving-glare-vs-polarized-lenses/
- Can I use FSA or HSA to buy prescription glasses online if I pay with PayPal? Yes. Corrective Single Vision, Progressive, Prescription Reading, Magnification Readers and Prescription Sunglasses are eligible US FSA and HSA medical vision expenses (0.00 non-prescription plano glasses and frame-only orders are excluded); pay via PayPal at checkout, then save your itemized USD PDF receipt from My Account → Orders → View to submit to your FSA/HSA administrator for reimbursement. URL: https://michaeloptical.com/answers/use-fsa-hsa-for-online-glasses/
- How do I hide thick edges on strong minus (-5.00 to -14.00 D) glasses? Pick a full-rim cellulose acetate frame with a 40 to 44 mm lens width whose geometric center sits within 3 mm of your pupillary distance, then pair it with 1.67 Thin High-Index (US$55/pair Single Vision Clear) for -4.50 to -6.50 D or 1.74 Ultra High-Index (US$100/pair) past -6.75 D. URL: https://michaeloptical.com/answers/how-to-hide-thick-lenses-high-myopia/
- My eye doctor wrote a plus (+) CYL for astigmatism: how do I enter it online? Transpose a plus-cylinder prescription in three optical steps: add the original SPH and +CYL algebraically for your new SPH, change the CYL sign from plus (+) to minus (-), and rotate the Axis by 90 degrees (add 90 if Axis is 1 to 90, or subtract 90 if Axis is 91 to 180), or email your slip to michael.optical.csr@gmail.com for free verification. URL: https://michaeloptical.com/answers/plus-to-minus-cylinder-prescription-conversion/
- Can I use my regular distance prescription for 24-inch computer monitors, or do I need office lenses? If your prescription has no ADD value (typically under age 38), your regular Single Vision distance Rx works comfortably at 20 to 26 inch monitors (from US$26.90 Clear or US$36.90 Blue-Light complete); if your prescription lists an ADD power (+0.75 to +3.50 D), choose Office Mid-Range or Near-Range Progressives (from US$76.90 Clear or US$91.90 Blue-Light complete, US$0 tier fee) so you do not tilt your chin up all day. URL: https://michaeloptical.com/answers/computer-glasses-distance-rx-to-intermediate/
- Why do my glasses keep sliding down my nose (or pinching behind my ears)? Glasses slide down when the nose bridge is more than 2 mm too wide, the temple arms extend too far before bending behind your ears, or thick front-heavy lenses pull the frame forward; pick adjustable nose-pad metal frames in the US$38.90 ZA Collection for low or narrow bridges, or match your current bridge within 1 to 2 mm in our 17-model millimetre matcher. URL: https://michaeloptical.com/answers/why-glasses-slide-down-nose-bridge-fit/
- Acetate vs. metal and titanium-alloy vs. TR90 frames: which material holds up best for daily wear? Choose hand-polished cellulose acetate (US$25.70 EM Collection) for hypoallergenic colour depth, custom heat-adjustable temples and thick-lens edge concealment; choose memory-flex TR90 (MICHAEL 8019, US$25.70) for featherlight sweat-resistant commuting; or choose titanium-alloy and metal frames (US$38.90 ZA Collection) when you want slim wire rims and adjustable nose pads. URL: https://michaeloptical.com/answers/acetate-vs-titanium-vs-tr90-eyeglass-frames/
- Are photochromic light-adaptive lenses worth it, or is a second pair of prescription sunglasses better? Choose Photochromic lenses (from US$56.90 complete in 1.56 Single Vision) if you walk indoors and outdoors on foot and hate carrying a second case; choose dedicated Polarized or Colored Prescription Sunglasses (from US$61.90 complete, or US$88.80 total paired with a US$26.90 Clear pair) if you drive in bright sun, visit beaches, or have astigmatism stronger than -4.00 CYL. URL: https://michaeloptical.com/answers/photochromic-lenses-vs-prescription-sunglasses/
- Does my eye doctor have to give me my prescription and PD so I can buy glasses online? Under the federal FTC Eyeglass Rule (16 CFR Part 456), US optometrists and ophthalmologists must provide your signed eyeglass prescription automatically right after your refractive exam at US$0 extra fee; pupillary distance (PD) is regulated at the state level, so if your clinic leaves PD blank, check a prior eyewear receipt or measure your Single or Dual PD in millimetres. URL: https://michaeloptical.com/answers/ftc-eyeglass-prescription-rights-expiration/
- How do I build a 2-pair prescription glasses bundle (everyday clear + sun or driving) under $100? Place two US$16.90 Everyday Picks or SSBC-T frames in the same cart so one flat US$5 contiguous US shipping fee covers both: a 1.56 Single Vision Clear pair (US$26.90) plus a 1.50 Dedicated Driving pair (US$48.90) totals US$80.80 delivered, or US$93.80 delivered with 1.56 Polarized Prescription Sunglasses (US$61.90), with US$0 astigmatism fee.

## Complete Buyer Q&A Answers, FAQs & Clinical Citations (/answers/)
### How much do prescription glasses actually cost online (without hidden fees)? (https://michaeloptical.com/answers/prescription-glasses-cost-calculator/)
Direct Answer: A complete pair of 1.56 single-vision prescription glasses with standard green anti-reflective and scratch-resistant coatings starts at US$26.90 before shipping (US$16.90 Everyday Picks frame + US$10 lenses, or US$31.90 delivered across the 48 contiguous US states and DC), with US$0 astigmatism surcharge down to -6.00 D.
- Q: Why do some $19 online glasses turn into $150 at checkout elsewhere? A: Many budget eyewear sites charge separate add-on fees for anti-reflective coating ($15 to $35), high-cylinder astigmatism ($15 to $39), and progressive corridor upgrades ($40 to $80). At MICHAEL Optical, base anti-reflective/scratch coatings, astigmatism correction down to -6.00 D, and progressive corridor tiers are all US$0 extra.
- Q: How much does US shipping add to the calculator subtotal? A: Standard delivery adds a flat US$5.00 per order to street addresses across the 48 contiguous United States and Washington, D.C. Custom optical lab preparation takes 3 to 5 business days, followed by an estimated 9 to 14 days in transit.
- Q: What if my prescription needs prism correction or 1.56 lined bifocals? A: Online self-service checkout covers Single Vision, Progressive, Reading, Driving, Non-Prescription and Frame-Only orders. Email michael.optical.csr@gmail.com before ordering if you want to check 1.56 Round-Top/Flat-Top bifocal pricing; prism prescriptions and mail-in re-lensing of customer frames are not offered online.

- Reference: Eyeglasses: What You Need to Know About Lenses & Coatings (American Academy of Ophthalmology (AAO)) — https://www.aao.org/eye-health/glasses-contacts/eyeglasses-what-to-know

### Can I buy glasses online with high astigmatism (-2.25 to -6.00 CYL) with no extra fee? (https://michaeloptical.com/answers/high-astigmatism-glasses-no-extra-fee/)
Direct Answer: Yes. MICHAEL Optical supports astigmatism cylinder (CYL) corrections down to -6.00 D on Standard Clear, Blue-Light Filtering and Colored Sun packages (and down to -8.00 D on 1.74 Advanced All-Day Progressives) at US$0 extra cylinder fee, provided you enter an exact Axis between 1° and 180° and an accurate Dual PD.
- Q: What if my doctor wrote my cylinder (CYL) with a plus (+) sign? A: Ophthalmologists sometimes write prescriptions in plus-cylinder notation. MICHAEL Optical’s online configurator uses standard negative-cylinder notation (-0.25 to -6.00 D). Ask your eye clinic for the minus-cylinder equivalent or email a photo of your Rx to michael.optical.csr@gmail.com before ordering so we can confirm the transposed values.
- Q: Can I order sunglasses if my astigmatism CYL is -4.50 or -5.50? A: Yes. While Polarized and Photochromic lenses cap CYL at -4.00 D, custom Colored Sun Tints (in Grey, Brown, Green, Purple, Pink or Blue up to 1.67 index) support CYL down to -6.00 D with US$0 cylinder surcharge.
- Q: What if my new high-astigmatism glasses feel slightly off when they arrive? A: Wear them for 3 to 5 days first so your visual cortex adapts to the updated lens curve, and check that the frame sits level on your ears and nose bridge. Every order includes a 30-day return or exchange window (1 per order) and a 365-day manufacturing defect warranty.

### Do I need 1.61, 1.67, or 1.74 high-index lenses for my prescription? (https://michaeloptical.com/answers/1-67-vs-1-74-high-index-lens-calculator/)
Direct Answer: For prescriptions within ±3.00 D, 1.56 (US$10/pair) or 1.61 (US$15/pair) is already slim; between ±4.00 D and ±6.50 D, 1.67 Thin High-Index (US$55/pair Single Vision) delivers the best thickness-to-price value; upgrade to 1.74 Ultra High-Index (US$100/pair Single Vision) when your power exceeds ±6.50 D (supported down to -20.00 / +16.00 D), and pair strong powers with a 40–44 mm frame.
- Q: Is 1.74 worth the US$45 upgrade over 1.67 for a -4.50 D prescription? A: Usually no. Around -4.00 D to -5.50 D, 1.67 Thin High-Index (US$55/pair in Single Vision Clear) already removes most visible edge bulk, while 1.74 (US$100/pair) shaves off roughly an extra fraction of a millimetre. Save 1.74 for powers past ±6.50 D or wider frame choices.
- Q: Do 1.67 and 1.74 high-index lenses come with anti-reflective coating included? A: Yes. High-index resins reflect slightly more surface light when uncoated, which is why every MICHAEL 1.61, 1.67 and 1.74 package includes our standard green anti-reflective and scratch-resistant base coating at US$0 extra.
- Q: Can I order 1.74 lenses in Polarized Sunglasses or Standard All-Day Progressives? A: Under our confirmed lens schedule, 1.74 Ultra High-Index is available on Single Vision and Upgrade/Advanced Progressive packages in Clear, Blue-Light, Photochromic and Photochromic + Blue-Light. Colored Sun, Polarized, Standard-tier Progressive and Office Progressive packages top out at 1.67 Thin High-Index.

### Can you buy progressive glasses online under $100 without getting dizzy? (https://michaeloptical.com/answers/progressive-glasses-online-under-100/)
Direct Answer: Yes. Pairing any US$16.90 Everyday Picks or SSBC-T frame with US$60 1.56 Clear Progressive lenses brings a complete no-line multifocal pair to US$76.90 before shipping (US$81.90 delivered), with Standard, Upgrade, Advanced and Office corridor tiers all included at US$0 tier surcharge; to avoid swim or dizziness, enter Dual monocular PD and choose a full-rim frame with sufficient vertical lens height.
- Q: What is the difference between Standard, Upgrade, Advanced and Office progressive tiers? A: Standard All-Day supports ADD +1.00 to +3.50 D in 1.56 to 1.67 (CYL to -4.00 D). Upgrade All-Day adds ADD from +0.50 D, 1.50 Driving and 1.74 Ultra High-Index. Advanced All-Day supports high astigmatism down to -6.00 D in 1.67 and -8.00 D in 1.74. Office Mid-Range and Near-Range dedicate the lens to desk and computer distances (1.50 to 1.67, CYL to -6.00 D). All four tiers add US$0 extra fee.
- Q: Why is Progressive Driving only US$32 to US$39 per pair? A: Under our confirmed customer schedule, Dedicated Day & Night Driving lenses use a flat all-inclusive pair rate (1.50 US$32, 1.61 US$36, 1.67 US$39) across both Single Vision and Progressive Multifocal, making a complete pair of progressive driving glasses possible from US$48.90 before shipping.
- Q: How long does it take to adapt to new online progressive lenses? A: Most first-time multifocal wearers adapt within 5 to 10 days of consistent full-day wear. Point your nose toward what you want to read and lower your gaze into the bottom zone rather than tilting your head back.

### How do I convert Single PD to Dual PD if my doctor didn't write it down? (https://michaeloptical.com/answers/single-to-dual-pd-converter/)
Direct Answer: Divide a Single binocular PD (50.0–80.0 mm) by 2 to get symmetrical right and left values for mild single-vision prescriptions (for example, 63 mm equals 31.5 mm OD and 31.5 mm OS); if your prescription exceeds ±4.00 D, includes high astigmatism, or uses progressive multifocal lenses, request or measure separate Dual monocular PD numbers (17.5–41.0 mm per eye) instead of dividing.
- Q: My prescription says 63/60 under PD. Which number do I enter? A: 63 mm is your Distance PD and 60 mm is your Near PD. Enter 63 mm for Single Vision distance glasses, Driving glasses, Sunglasses and Progressive Multifocal glasses (our lab automatically insets the near corridor from your distance PD). Enter 60 mm only when ordering dedicated single-vision Reading glasses.
- Q: Why do my Dual PD numbers add up to an odd half-millimetre like 31.5 and 32.0? A: Human faces are naturally slightly asymmetrical. One eye often sits 0.5 mm to 1.5 mm farther from the center of the nose bridge than the other, which is why our Dual PD selector supports 0.5 mm increments from 17.5 mm to 41.0 mm per eye.
- Q: Can I just use the 63 mm adult average PD to place my order now? A: We strongly advise against guessing an average PD, especially on prescriptions stronger than ±2.00 D or any progressive lens. Taking two minutes to call your last optical shop or measure carefully with a millimetre ruler prevents eye strain and remakes.

### What do the 3 numbers inside my glasses mean (e.g. 49-22-145), and which frames fit me? (https://michaeloptical.com/answers/glasses-frame-size-numbers-matcher/)
Direct Answer: The three numbers stamped inside your temple arm represent Lens Width × Bridge Width × Temple Length in millimetres (for example, 49-22-145 means 49 mm lenses, a 22 mm nose bridge and 145 mm arms); stay within ±2 mm on lens width and ±1–2 mm on bridge width of a comfortable pair you already wear, and pick 40–44 mm lens widths for narrow faces or strong prescriptions.
- Q: What if the numbers inside my old glasses have rubbed off? A: Use a flat millimetre ruler: measure one lens horizontally across its widest inner opening for Lens Width, measure the shortest gap between the two lenses across the nose for Bridge Width, and measure the arm from the hinge screw to the ear tip for Temple Length.
- Q: Which MICHAEL frames are smallest for petite faces or strong minus prescriptions? A: In the EM Acetate collection, MICHAEL EM23107 (40 × 28 × 143 mm), EM23218 (42 × 24 × 141 mm), EM23105 (42 × 28 × 144 mm), EM23103 (43 × 31 × 144 mm) and FT2403 Brown/Black (44 × 27 × 142 mm) offer compact lens apertures that minimize edge thickness.
- Q: Which frame material feels lightest for all-day wear? A: MICHAEL 8019 (51 × 25 × 148 mm, US$25.70) is made from flexible TR90 thermoplastic polymer for featherlight comfort, while our Everyday Picks & SSBC-T series (US$16.90) and ZA Titanium/Metal series (US$38.90) also include lightweight everyday profiles.

### What lenses reduce night driving headlight glare: polarized, photochromic, or driving lenses? (https://michaeloptical.com/answers/night-driving-glare-vs-polarized-lenses/)
Direct Answer: Never wear dark polarized sunglasses at night, and note that standard UV photochromic lenses stay mostly clear inside a car because windshields block UV light; choose high-transmission Day & Night Driving Lenses (all-inclusive US$32 in 1.50, US$36 in 1.61, or US$39 in 1.67 for both Single Vision and Progressive) for night headlight glare, and Polarized Sunglasses (from US$45) for bright daytime highways.
- Q: Why do oncoming LED headlights create starbursts on my current glasses? A: Fine micro-scratches from dry wiping, smudged skin oils, uncoated lens surfaces, or an outdated astigmatism (CYL) prescription scatter point-source headlights into halos. Fresh anti-reflective or Dedicated Driving lenses paired with an updated CYL prescription cut internal lens reflections noticeably.
- Q: Are Dedicated Driving Lenses offered in Non-Prescription (0.00 plano)? A: Yes. If you have 20/20 distance vision or wear contact lenses, 1.50 Non-Prescription Dedicated Driving lenses cost US$32/pair (complete pair from US$48.90 with a US$16.90 Everyday Picks frame).
- Q: What is the CYL astigmatism limit on Driving and Polarized lenses? A: Dedicated Driving and Polarized Sunglasses support CYL from 0.00 to -4.00 D (with US$0 cylinder surcharge). If your CYL is between -4.25 and -6.00 D, select Standard Clear (with included anti-reflective base coating) for night driving and Colored Sun Tints for daytime sun.

### Can I use FSA or HSA to buy prescription glasses online if I pay with PayPal? (https://michaeloptical.com/answers/use-fsa-hsa-for-online-glasses/)
Direct Answer: Yes. Corrective Single Vision, Progressive, Prescription Reading, Magnification Readers and Prescription Sunglasses are eligible US FSA and HSA medical vision expenses (0.00 non-prescription plano glasses and frame-only orders are excluded); pay via PayPal at checkout, then save your itemized USD PDF receipt from My Account → Orders → View to submit to your FSA/HSA administrator for reimbursement.
- Q: Does MICHAEL Optical bill VSP, EyeMed or Davis Vision directly? A: No. MICHAEL Optical operates direct-to-consumer online to keep complete prescription glasses starting at US$26.90 before shipping without insurance markups. You can submit your itemized USD order receipt for out-of-network vision insurance reimbursement where your plan allows.
- Q: Are high-index upgrades (1.67 or 1.74), blue-light filters and photochromic lenses covered by FSA/HSA? A: Yes, when ordered as part of a corrective prescription lens pair, functional lens options such as 1.61/1.67/1.74 high-index, blue-light filtering, photochromic, driving and polarized sun treatments are generally covered alongside the frame.
- Q: Which date counts for year-end FSA deadlines: order date or delivery date? A: Most US FSA administrators go by the date of purchase/service shown on your paid order receipt rather than the carrier delivery date, though you should confirm your specific plan’s grace period or run-out deadline.

### How do I hide thick edges on strong minus (-5.00 to -14.00 D) glasses? (https://michaeloptical.com/answers/how-to-hide-thick-lenses-high-myopia/)
Direct Answer: Pick a full-rim cellulose acetate frame with a 40 to 44 mm lens width whose geometric center sits within 3 mm of your pupillary distance, then pair it with 1.67 Thin High-Index (US$55/pair Single Vision Clear) for -4.50 to -6.50 D or 1.74 Ultra High-Index (US$100/pair) past -6.75 D.
- Q: What is the strongest nearsighted prescription MICHAEL Optical makes online? A: Single Vision 1.74 Ultra High-Index Clear, Blue-Light and Photochromic packages support Sphere (SPH) powers down to -20.00 D (and up to +16.00 D in Clear), with astigmatism cylinder (CYL) included at US$0 extra down to -6.00 D on Clear and Blue-Light lenses.
- Q: Why does FT2403 Clear fit differently than FT2403 Brown or Black for strong prescriptions? A: MICHAEL FT2403 uses two distinct mould sizes by colourway: Brown and Black measure 44 x 27 x 142 mm (compact, ideal for strong minus lenses), whereas Crystal Clear measures 52 x 22 x 143 mm. Always pick Brown or Black on FT2403 when minimizing edge thickness.
- Q: Does frame colour affect how noticeable high-myopia "power rings" look from the front? A: Yes. Dark tortoise, espresso brown and solid black acetate rims absorb light scattered inside the ground lens edge, whereas crystal-clear transparent rims let edge reflections pass through.

### My eye doctor wrote a plus (+) CYL for astigmatism: how do I enter it online? (https://michaeloptical.com/answers/plus-to-minus-cylinder-prescription-conversion/)
Direct Answer: Transpose a plus-cylinder prescription in three optical steps: add the original SPH and +CYL algebraically for your new SPH, change the CYL sign from plus (+) to minus (-), and rotate the Axis by 90 degrees (add 90 if Axis is 1 to 90, or subtract 90 if Axis is 91 to 180), or email your slip to michael.optical.csr@gmail.com for free verification.
- Q: Why is Axis 000 invalid on online eyeglass forms? A: In ophthalmic optics, 0 degrees and 180 degrees represent the same horizontal meridian, and prescriptions always record horizontal axis as 180. If your doctor wrote x180 on a plus-cylinder Rx, subtracting 90 gives Axis 90; if they wrote x90, adding 90 gives Axis 180.
- Q: Does transposing from +CYL to -CYL change my lens thickness or price? A: No. Plus-cylinder and minus-cylinder notations describe the exact same physical curve on the finished lens. At MICHAEL Optical, cylinder corrections down to -6.00 D add US$0 extra fee.
- Q: Can MICHAEL support double-check my transposed numbers before I pay? A: Yes. Email a clear photo of your signed paper prescription to michael.optical.csr@gmail.com and our team will reply with the exact OD and OS minus-cylinder values to select in the configurator.

### Can I use my regular distance prescription for 24-inch computer monitors, or do I need office lenses? (https://michaeloptical.com/answers/computer-glasses-distance-rx-to-intermediate/)
Direct Answer: If your prescription has no ADD value (typically under age 38), your regular Single Vision distance Rx works comfortably at 20 to 26 inch monitors (from US$26.90 Clear or US$36.90 Blue-Light complete); if your prescription lists an ADD power (+0.75 to +3.50 D), choose Office Mid-Range or Near-Range Progressives (from US$76.90 Clear or US$91.90 Blue-Light complete, US$0 tier fee) so you do not tilt your chin up all day.
- Q: Can I subtract half my ADD power myself to order cheaper Single Vision computer glasses? A: Ask your optometrist to confirm your exact 24-inch intermediate sphere before ordering Single Vision computer glasses, or simply enter your full unmodified Distance Rx + ADD into MICHAEL’s Office Progressive tier (US$60 Clear / US$75 Blue-Light in 1.56), which calculates both monitor and keyboard zones automatically.
- Q: Which PD do I enter for computer or Office Progressive glasses? A: For Office Progressive lenses, enter your Dual Monocular Distance PD (for example, 31.5 mm OD / 32.0 mm OS) so our lab insets the intermediate and near corridors accurately. Only enter Near PD (the smaller number on a 64/61 slip) when ordering dedicated single-vision Reading glasses.
- Q: Do Blue-Light lenses look yellow on video calls? A: MICHAEL Optical’s clear-base Blue-Light Filtering resin uses a subtle violet-blue surface interference filter rather than an amber dye, keeping skin tones natural on webcam calls while attenuating high-energy 400 to 455 nm screen glare.

### Why do my glasses keep sliding down my nose (or pinching behind my ears)? (https://michaeloptical.com/answers/why-glasses-slide-down-nose-bridge-fit/)
Direct Answer: Glasses slide down when the nose bridge is more than 2 mm too wide, the temple arms extend too far before bending behind your ears, or thick front-heavy lenses pull the frame forward; pick adjustable nose-pad metal frames in the US$38.90 ZA Collection for low or narrow bridges, or match your current bridge within 1 to 2 mm in our 17-model millimetre matcher.
- Q: Why does frame slipping make progressive or high-astigmatism glasses blurry? A: Progressive lenses stack distance, computer and reading powers vertically within a few millimetres. If a loose bridge lets your glasses slide 3 mm down your nose, your pupils look above the distance optical center and you have to tilt your head back to reach the reading zone.
- Q: Can TR90 thermoplastic temple arms be heat-bent like cellulose acetate? A: No. MICHAEL 8019 uses memory-flex TR90 thermoplastic polymer, which springs back to its moulded shape for featherlight grip rather than taking permanent heat bends. Choose cellulose acetate (16 EM models) or metal core-wire temples when you need custom ear-tip bending.
- Q: What if my new MICHAEL glasses do not fit my nose bridge when they arrive? A: Try a quick nose-pad or ear-tip temple adjustment first if the frame is close. If the bridge or front width is genuinely the wrong size, every MICHAEL Optical order includes one return or exchange within 30 days of delivery.

### Acetate vs. metal and titanium-alloy vs. TR90 frames: which material holds up best for daily wear? (https://michaeloptical.com/answers/acetate-vs-titanium-vs-tr90-eyeglass-frames/)
Direct Answer: Choose hand-polished cellulose acetate (US$25.70 EM Collection) for hypoallergenic colour depth, custom heat-adjustable temples and thick-lens edge concealment; choose memory-flex TR90 (MICHAEL 8019, US$25.70) for featherlight sweat-resistant commuting; or choose titanium-alloy and metal frames (US$38.90 ZA Collection) when you want slim wire rims and adjustable nose pads.
- Q: Which frame material is lightest if heavy glasses give me headaches? A: TR90 thermoplastic (MICHAEL 8019 at US$25.70) and slim titanium-alloy wire profiles in the US$38.90 ZA Collection carry the lowest frame gram weight. Pair them with 1.61 (US$15) or 1.67 (US$55) high-index resin so the lenses do not add front weight back.
- Q: Do semi-rimless (nylon-cord) metal frames chip more easily than full-rim acetate? A: Standard 1.50 or 1.56 lenses can chip along grooved semi-rimless nylon cords if dropped. When ordering half-rim styles in the ZA Collection, select 1.61 High-Index (US$15), 1.61 Pro Extra-Hardened (US$30) or 1.67 Thin High-Index (US$55), whose tougher resin matrices hold grooved edges cleanly.
- Q: Why does white oxidation ("blooming") sometimes appear on old acetate temples? A: Natural cotton-derived cellulose acetate gradually releases moisture if washed in hot tap water or left on a hot car dashboard. Rinse only in cool water with mild dish soap and store frames in their case out of dashboard heat.

### Are photochromic light-adaptive lenses worth it, or is a second pair of prescription sunglasses better? (https://michaeloptical.com/answers/photochromic-lenses-vs-prescription-sunglasses/)
Direct Answer: Choose Photochromic lenses (from US$56.90 complete in 1.56 Single Vision) if you walk indoors and outdoors on foot and hate carrying a second case; choose dedicated Polarized or Colored Prescription Sunglasses (from US$61.90 complete, or US$88.80 total paired with a US$26.90 Clear pair) if you drive in bright sun, visit beaches, or have astigmatism stronger than -4.00 CYL.
- Q: Why would someone choose Colored Sun Tints over Polarized Sunglasses at the same US$45 price? A: Two reasons: Colored Sun Tints support high astigmatism CYL down to -6.00 D (versus -4.00 D on Polarized), and non-polarized sun tints never black out polarized car head-up displays (HUDs), cockpit instruments or older LCD fuel-pump screens when you tilt your head.
- Q: Do custom sun tint colours (Grey, Brown, Green, Purple, Pink or Blue) cost extra? A: No. All six Classic and Custom sun tint colours carry US$0 colour surcharge inside Colored Sun, Polarized and Photochromic packages where supported.
- Q: How much does it cost to buy both Clear glasses and Polarized Sunglasses together? A: On US$16.90 Everyday Picks frames, one 1.56 Clear pair (US$26.90) plus one 1.56 Polarized Sun pair (US$61.90) totals US$88.80 before flat US$5 contiguous US shipping (US$93.80 delivered for two complete prescription pairs).

### Does my eye doctor have to give me my prescription and PD so I can buy glasses online? (https://michaeloptical.com/answers/ftc-eyeglass-prescription-rights-expiration/)
Direct Answer: Under the federal FTC Eyeglass Rule (16 CFR Part 456), US optometrists and ophthalmologists must provide your signed eyeglass prescription automatically right after your refractive exam at US$0 extra fee; pupillary distance (PD) is regulated at the state level, so if your clinic leaves PD blank, check a prior eyewear receipt or measure your Single or Dual PD in millimetres.
- Q: Can an eye clinic charge $25 just to hand me my eyeglass prescription? A: No. Under 16 CFR § 456.2 of the FTC Eyeglass Rule, a prescriber cannot charge an extra fee on top of the eye exam to release your eyeglass prescription, nor require you to buy frames in-office as a condition of the exam.
- Q: Why does my prescription paper have two different PD numbers like 64 / 61? A: 64 mm is your Distance PD (when looking straight ahead at 20 feet) and 61 mm is your Near PD (when your eyes converge inward to read at 16 inches). Enter 64 mm for Single Vision distance, Driving, Sun and Progressive glasses; enter 61 mm only for dedicated single-vision Reading glasses.
- Q: Do I need to upload a scan of my paper prescription during MICHAEL checkout? A: Online self-service checkout lets you enter your confirmed OD, OS and PD numbers directly on the product configurator without waiting on manual document approval, and prints those exact Rx values onto your itemized USD order receipt. If you want a human optician team check before paying, email michael.optical.csr@gmail.com.

### How do I build a 2-pair prescription glasses bundle (everyday clear + sun or driving) under $100? (https://michaeloptical.com/answers/two-pair-prescription-glasses-bundle-under-100/)
Direct Answer: Place two US$16.90 Everyday Picks or SSBC-T frames in the same cart so one flat US$5 contiguous US shipping fee covers both: a 1.56 Single Vision Clear pair (US$26.90) plus a 1.50 Dedicated Driving pair (US$48.90) totals US$80.80 delivered, or US$93.80 delivered with 1.56 Polarized Prescription Sunglasses (US$61.90), with US$0 astigmatism fee.
- Q: Can I order two progressive pairs near $120 to $130 if I have $150 left in my FSA? A: Yes. One 1.56 Clear Progressive pair on a US$16.90 frame (US$76.90) plus one 1.50 Progressive Day & Night Driving pair (US$48.90) plus US$5.00 shipping totals US$130.80 delivered for two complete no-line multifocal pairs.
- Q: Can two family members put their different prescriptions into one cart? A: Most FSA/HSA administrators allow eligible prescriptions for you, your spouse and tax dependents on the same claim, though we recommend placing separate orders per person if you want each order receipt to show one patient’s Rx clearly or keep separate 30-day exchange eligibility per person.
- Q: Does adding a second pair slow down optical lab preparation? A: Both pairs enter custom surfacing in parallel during our standard 3 to 5 business day optical lab preparation and quality-inspection window, then dispatch together in one tracked US$5.00 package (estimated 9 to 14 days in transit).

Package eligibility is checked separately; current standard packages allow total PD up to 80 mm.
- Astigmatism (CYL) carries a US$0 extra surcharge across all lens tiers; whenever CYL is not zero, entering an Axis (1°–180°) is mandatory.
- High astigmatism (CYL -4.25 to -6.00) is supported in 1.61–1.74 indices for Standard Clear, Blue-Light and Colored Sun Tint packages.

### Understanding Pupillary Distance (PD) Before Ordering (https://michaeloptical.com/?bal_page=measure-pd)
Learn the difference between Single PD and Dual (Monocular) PD, why optical centration matters, and how to enter your confirmed measurement at MICHAEL.
- Pupillary Distance (PD) aligns the optical centre of each prescription lens directly in front of your pupils.
- The MICHAEL form accepts Single Binocular PD (50.0–82.0 mm) and Dual Monocular PD (17.5–41.0 mm per eye) in 0.5 mm increments. Package eligibility is checked separately; current standard packages allow total PD up to 80 mm.

### How to Choose the Best Frames for Progressive Lenses (https://michaeloptical.com/?bal_page=choose-progressive-frames)
Why vertical lens height, bridge stability and frame geometry matter when ordering no-line progressive multifocal glasses.
- Choose frames with generous vertical lens height (typically 30 mm or taller) so distance, intermediate computer and near reading zones have ample room.
- Full-rim acetate and TR90 frames with stable bridge widths (22–32 mm) prevent progressive corridors from slipping below your pupils.
- Top MICHAEL progressive-friendly models include 2622, 8836, 23104, 23220, 8019 (TR90), EM8804, EM23103 and EM23105 (all US$25.70 for the EM frame).

### How to Adapt to Progressive Lenses (https://michaeloptical.com/?bal_page=adapt-progressives)
Practical habits for your first 7 to 14 days wearing new progressive glasses—how to point your nose, align your posture for screens, and navigate stairs.
- Most wearers adapt to new progressive lenses within 3 to 14 days by wearing them consistently from morning.
- Point your nose toward what you want to view and adjust your gaze vertically through the top (distance), middle (computer) and bottom (reading) zones.
- Tuck your chin slightly when walking down stairs so you look through the upper distance portion rather than the lower reading magnification zone.

Comparing traditional polycarbonate lenses against MICHAEL’s 1.56, 1.61, 1.61 Pro, 1.67 and 1.74 high-index optical resin lineup.
- MICHAEL uses precision-cast 1.50, 1.56, 1.61, 1.61 Pro, 1.67 and 1.74 optical resin lenses rather than 1.59 polycarbonate.
- 1.61 and 1.61 Pro High-Index resin lenses are thinner than 1.59 polycarbonate and offer higher optical clarity (less peripheral colour fringing).
- For lightweight everyday durability, pair 1.61 Pro lenses with our flexible MICHAEL 8019 TR90 frame or any full-rim acetate frame.

### Trivex vs. High-Index Optical Lenses Guide (https://michaeloptical.com/?bal_page=trivex)
Understand what Trivex (1.53) is, how it compares with 1.56 and 1.61 optical resin lenses, and which lightweight options are available at MICHAEL.
- Trivex is a 1.53 low-index urethane material; MICHAEL instead stocks 1.56, 1.61, 1.61 Pro, 1.67 and 1.74 high-index optical resins.
- For mild prescriptions (within ±2.00 D), 1.56 (Single Vision index fee +US$5) and 1.61 (Single Vision index fee +US$10) provide crisp clarity and thinner profiles than 1.53 lenses.
- For stronger durability in everyday wear, choose 1.61 Pro (index fee: +US$25 Single Vision / Readers, +US$45 Progressives, added to the function fee).

### Durable Frames & Active Everyday Eyewear Guide (https://michaeloptical.com/?bal_page=impact)
How to choose resilient frame materials (TR90 vs. Acetate) and 1.61 Pro high-index lenses for busy routines, travel and active everyday wear.
- Full-rim cellulose acetate (16 models) and flexible TR90 thermoplastic (MICHAEL 8019) protect lens edges around the entire 360° perimeter.
- 1.61 Pro Extra-Hardened High-Index lenses provide reinforced surface scratch resistance for busy daily commutes and travel.
- Dress eyewear is built for everyday lifestyle use; always wear certified safety goggles for power tools, lab work or impact sports.

### Light-Sensitivity & Comfort Tint Guide (https://michaeloptical.com/?bal_page=fl-41)
Exploring rose/pink tints, blue-light filtering and photochromic options for harsh indoor lighting, plus when to consult your eye doctor for clinical light sensitivity.
- MICHAEL does not make clinical medical device claims or sell therapeutic FL-41 migraine filters.
- For everyday non-medical visual comfort under harsh office LEDs or sunlight, choose Blue-Light Filtering, Photochromic + Blue-Light (including Pink/Purple/Brown), or Colored Sun Tints.
- Consult your neuro-ophthalmologist or optometrist if you require a prescribed medical spectral filter.

### How to Care For, Clean & Adjust Your Glasses (https://michaeloptical.com/?bal_page=adjust-glasses)
Keep your MICHAEL acetate or TR90 frames and coated lenses in top condition—daily cleaning habits, storage tips, and why professional optician adjustments matter.
- Rinse lenses with lukewarm water and mild lotion-free dish soap, then dry with a clean microfibre cloth—never wipe dusty lenses dry with paper towels.
- Keep cellulose acetate frames away from high heat (car dashboards, saunas, hair dryers) to preserve bridge and temple alignment.
- Never bend frames cold or with household heat; visit a local optician with a professional optical frame warmer for temple or nose-bridge adjustments.

### Full-Rim Frame Care & Lens Handling Guide (https://michaeloptical.com/?bal_page=replace-full-rim)
How full-rim acetate and TR90 frames secure your prescription lenses, and what to know before having lenses replaced or serviced.
- All 17 current MICHAEL frames use full-rim construction, offering 360-degree lens edge protection and concealing high-prescription thickness.
- If you buy Frame Only (from US$16.90 on Everyday Picks or US$25.70 on EM frames), any qualified local optician can warm the rim in an optical frame warmer and mount your lenses.
- Because complete Single Vision glasses start at US$26.90 on Everyday Picks (US$16.90 frame + US$10 lenses) or US$35.70 on EM frames (US$25.70 frame + US$10 lenses), ordering a complete new pair online is often more economical than local re-lensing.

### Double-Bridge & Specialty Frame Care Guide (https://michaeloptical.com/?bal_page=replace-half-rim)
How to care for double-bridge, angular and combination frames, and why specialty rim constructions require professional optical handling.
- Sculptural and double-bridge MICHAEL styles (such as 8804, EM8804, 2406 and FT1001) should always be put on and removed with both hands.
- Semi-rimless nylon-cord frames require a specialized ribbon-mounting tool and higher-tensile lens materials (such as 1.61, 1.61 Pro or 1.67).
- Never cut or pull a suspension cord at home; always rely on a professional optician for specialty rim servicing.

- Pairing a primary everyday pair (from US$26.90 complete w/ 1.56 Rx on Everyday Picks or US$35.70 on EM Acetate) with a task-specific second pair (Polarized Sunglasses, Driving Glasses or Computer Readers) reduces wear and tear on both frames.
