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

​​​Pricing Details:

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. 

Sight4All is sensitive to providing a high value product at an affordable price.  As we get closer to the ultimate distribution of TESA, information about pricing will be made available.
