Scan your glasses to get your prescription details.

It’s free! You can scan as many pairs of glasses as you want, and it won’t cost you a thing.

Once you’ve downloaded the app, most users complete the scan in 3-5 minutes.

The online lens scanner provides instant results! You’ll get your prescription details right on the screen as soon as your scan is complete. We recommend saving your results to a Hello Eyes account or taking a screenshot you can use for easy reference.

The lens scanner provides details for single-vision prescriptions only, including astigmatism.

If you wear multifocal, progressive, or bifocal lenses, that means you need correction for more than one field of vision (i.e. to see both near and far away), and the lens scanner will not work on these types of lenses.

Specifically, the lens scanner can read prescriptions in this range: -6.00 - +3.00, with a cylinder up to -2.50.

Great question! You will need the Hello Eyes app, downloaded to your smartphone. A computer with a 12" screen or larger. And a standard-sized card with a magnetic strip, like a debit card or library card, to help us with scaling.

Unfortunately, no. Right now, we can only scan single-vision lenses and provide details.

Yes! If you’re happy with your current prescription, but unsure of the prescription details in your current glasses, you can use this tool to extract those details and apply them to your next pair.

No, the lens scan tool (also known as a lensometer) pulls the optical parameters from an existing pair of glasses. It cannot provide a brand new prescription or replace an eye exam. This tool is helpful if you want to purchase new glasses using the same prescription in your current pair. Your prescription must be current and valid to order new glasses. The lens scan tool has been tested and meets industry guidelines for accuracy. See full terms and conditions.
