If you choose to enter in your Rx on the ordering pages, the system will make some lens recommendations based on the power of your lenses.  We offer the following materials of lenses:

1.60 High-Index Lenses

We use an impact resistant version of 1.60 that is 25% thinner and lighter than standard plastic lenses. Our 1.60 High-Index lenses have 25% higher optical clarity than standard Polycarbonate lenses, and this is our default material that is included in the base price of all clear and blue light lenses.

1.67 High-Index Lenses

These High-Index lenses are up to 35% thinner than standard plastic lenses and work well for those with Rx’s over +/-3.00.

1.74 High-Index Lenses

These Bio-based lenses are the thinnest available option that are up to 45% thinner than standard plastic lenses and work well for those with Rx’s over +/-6.00.
