Get the App

Get the App:

Once TESA is released, getting started will be easy. ​Just follow these four simple steps:

1. Acquire an iPhone 7+

Cellular connectivity is not required unless there is no wifi connection available.

2. Go to the App Store and download the TESA app

Access to the app is free.​ No credit card is needed during the free evaluation period. Your state license number will be used to credential you as a qualified eye care provider.


Enjoy unlimited use of TESA for one month at no charge.

4. Subscription

When the free evaluation period concludes, the service will automatically stop—you don’t need to remember to cancel it. Subscribe by providing a secure credit card authorization. No obligation or long-term contract. Cancel at any time.
