High Cylinder Lenses

Custom made for high astigmatism prescriptions

Why Do We Charge Extra for High Cylinder?

The short answer is: Custom Lenses. We stock lenses for some prescriptions but we custom make most prescriptions, which includes high cylinder values. High cylinder stock lenses are not the best, so we custom make your lenses from scratch to get the best possible vision.

Built for High Astigmatism

Custom digital lenses are well-suited for high cylinder prescriptions, offering wider, sharper vision zones. These lenses use digital surfacing and behavioral AI to minimize distortions — the swim effect — allowing for faster adaptation, even with high astigmatism corrections.

We are the only online prescription eyeglass company making lenses from scratch for high cylinder prescriptions and most prescriptions in general. This way your lenses come out thinner and clearer.

What Counts as High Cylinder?

Your prescription includes a CYL value that indicates the degree of astigmatism. Here’s a general reference:

Up to 1.00 Mild — Polycarbonate
1.00 – 2.00 Moderate — Polycarbonate or High Index, prescription dependent
2.00 + High cylinder — custom lenses required

A Note on Lens Selection

If you do have a strong prescription, please make sure to order the thinnest lenses to get the best vision possible.

Vision Insurance Information

How Insurance Reimbursement Works

Unfortunately, we don't have any direct partnerships with vision insurance providers, but we can assist you in getting a reimbursement for your purchase after you have paid in full at the time of purchase. In order to be reimbursed, you will first need to fill out a form from your insurance provider. After you fill out their reimbursement form, you will need to provide an itemized receipt, which we can provide you with once you have completed your purchase. We've provided some links below of popular vision insurance providers to help you get started.

Please contact your vision insurance for more information on how to file for a reimbursement.

If you have any question or you need an itemized receipt, please email us at info@nerdyframes.com

FSA & HSA Payments

We accept both FSA and HSA payments, as long as they are in the form of a credit or debit card. After you have had completed a purchase with your FSA/HSA, you can then file for a reimbursement with your vision insurance provider.
