This tool uses your iris diameter as a built-in scale reference — the human iris is always 11.7mm. No card or object needed. Simply look at the camera.

Our AI detects 468 facial landmarks, including your iris edges, in real time. By comparing the known iris size to the pixel distance between your pupils, it calculates your PD to within ±1–1.5mm — comparable to the precision typically achieved during an in-store PD measurement. Now that we've measured it, you might as well put it to good use.

  • I.Find good, even lighting — face a window or a bright light source. Avoid backlighting.
  • II.Hold your device comfortably — the tool will guide you to the ideal distance automatically.
  • III.Look at the small camera lens — it's the tiny dot at the top of your screen, above your reflection. Stay still.
  • IV.When the confidence meter turns green, your measurement is captured automatically.

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.
