Opto is optimized for use with retina-display iPads (3rd generation and later). Some exercises require the specially designed G-Labs stereoscope for iPad (see below).

*Required Hardware/Accessories:

Not all tools in Opto require additional hardware beyond your iPad. If required, necessary accessories are indicated in the exercise description before purchasing. Some exercises are designed to be used with anaglyph 3D glasses, styluses, or the G-Labs STEREOSCOPE FOR iPAD. This brewster-type stereoscope has been developed specifically to work with your 3rd generation or higher iPad and the Opto app (although it can be used with many other 3D apps as well). Order your iPad stereoscope on the G-Labs website www.gerull-labs.com

Recommended Uses for Opto:

● Use the app in the clinic while you work with your patients during their visit
● Recommend exercises for your patients to download onto their own iPads
●Use the My Routine feature to set up a weekly practice routine for the patient to follow on their own device
● Some clinics may have additional iPads and G-Labs Stereoscopes available for patients to borrow to use Opto at home. (Apple allows one iTunes account to be used on up to 5 devices).
