Lensabl's prescription scanner is the easiest online solution for renewing your prescription. This easy-to-use tool uses your cell phone, a computer, a card (ex. credit card or photo ID), and your current glasses to see if your prescription has changed.

Our app lets you get the prescription measurements from your current eyeglasses. It’s easy to use and totally free.

We enter your results into a standard prescription format, so you can easily order glasses online.

Now, you can order glasses online without a worry. Time to find a new frame!

Here's What You Need

You can use our online prescription reader with tools you already have. You'll need:

Group 7 A smartphone with a functional camera.

You can find out if your phone is compatible online.

Group 4 A computer with a 12-inch to 27-inch screen.
Fill 1 Any magnetic card, like a credit card, for true calibration.
Fill 1 Your current eyeglasses.

* Our app pulls the optical parameters from your current glasses, so it doesn't replace an eye exam or give you a new prescription. Your prescription must be current and valid to order new glasses. See full terms and conditions for more information.
