MICHAEL / Eyewear Answers & Calculators

Can I buy glasses online with high astigmatism (-2.25 to -6.00 CYL) with 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.

Supported Cylinder (CYL) Limits by Lens Package

High-cylinder lenses require strict optical boundaries so the finished pair stays clear and distortion-free. Our configurator enforces the confirmed CYL limits below automatically:

Three Precautions That Keep High-Astigmatism Online Glasses Sharp

  1. Double-check your Axis degree (1° to 180°): Above -2.25 CYL, even a few degrees of axis entry error causes noticeable blur. Copy the exact whole-number Axis for OD (right eye) and OS (left eye) from your written prescription, and never swap 090 with 009 or 180 with 080.
  2. Enter Dual Monocular PD instead of a guessed average: Ask your optometrist for separate right and left PD measurements (for example, 31.0 / 32.0 mm) so each cylinder meridian aligns directly over your pupil.
  3. Choose a compact full-rim frame (40–45 mm lens width): Smaller full-rim acetate frames like MICHAEL EM23107 (40 mm), EM23218 (42 mm) and FT2403 Brown/Black (44 mm) hold lens rotation steady and trim edge thickness.

Follow-Up Questions Buyers Ask

What if my doctor wrote my cylinder (CYL) with a plus (+) sign?

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.

Can I order sunglasses if my astigmatism CYL is -4.50 or -5.50?

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.

What if my new high-astigmatism glasses feel slightly off when they arrive?

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.
