     The Opto Pro Library is currently organized into in 3 main categories of resources: red/cyan, stereoscope, and other. You can also search for a specific exercise by typing in the search box. Tap on any exercise to see a description. More detailed clinical descriptions and how-to videos are also available on our website. In the description box, you will also be informed if this activity requires any additional hardware such as red/cyan glasses or the g-labs Stereoscope for iPad. Some exercises do not require any additional equipment. To purchase any required hardware, visit our online store.

To allow you to customize the experience to the needs of your practice, you choose which exercises you would like to purchase for your library.

Once an item is purchased, it is yours for unlimited use.

In the settings, turn on clinic mode to launch exercises directly from the library screen, or create a personal profile to customize individual practice routines.

You can create multiple user profiles, and build a separate routine for each patient.

Add one of the exercises that you own to My Routine by tapping the [+] button. A check mark appears to show that it is added. Swipe right to left to access your routine. You can add, remove, and re-order your activities at any time.

Results for each exercise completed are recorded in the reports section (to access the reports, look for the icon in the upper right that looks like a paper). The date, duration, results, and even a screenshot when applicable, are saved for your reference. If a user is signed in to his or her profile, they will also get to indicate their personal feelings on the difficulty of the exercise. You can print or email these reports directly from Opto, wether you are in the clinic or practicing at home.

Opto Pro is a collaborative endeavor by the G-Labs team and the worldwide vision care community. We would love to hear your suggestions, ideas, and comments. With your help, we will continue to grow the library within Opto Pro and provide you with resources to make your practice more modern, engaging, and effective.
