Frequently Asked Questions
Have a question that is not listed here?
Send us a message and we will respond directly to you.
Can I use my iPad mini?
Opto is designed for full size iPads only. iPad minis are not recommended and some exercises may not display properly.
Do I need to purchase a G-Labs Stereoscope to use the Opto app?
No. Not all of the tools in the app use a stereoscope. Some require 3D glasses (Red/Cyan or Red/Blue), others require no accessories at all! If any special equipment is required, it will be noted in the description of the exercise before you purchase it.
When will more items be added to the Opto Library?
More items are in production now and will be added regularly! Is there something you would like to see included? Please send us a message and let us know!
Once I have purchased and exercise within the app, how many uses do I get?
Unlimited. Once you have purchased an exercise there is no limit to how much you can use it.
How many use profiles can be stored on one iPad?
Up to 200 user profiles may be stored at any given time. Profiles include a user name, profile picture, and the ability to create/save a customized practice routine. Profiles may be deleted once they are no longer required.
For my patients to use Opto at home, do I have to lend them my iPad?
Each clinic may have a different policy. Some recommend patients download the app on their own iPad and purchase the exercises they need for home practice. Others have multiple iPads in their clinic which they allow patients to borrow after signing an agreement regarding damaged/lost items.
how can i access my purchased exercises from a new or ADDITIONAL ipad?
Apple allows you to associate your iTunes account with several devices. Once you purchase an exercise, it will be available on devices that are signed in to the same iTunes account. Simply use the "Restore Purchased Exercises" button in the setting screen of Opto. For detailed instructions on how to restore your purchased exercises on a new or additional device, please watch this short video.
What are the system/hardware requirements to run the Opto app?
Opto is optimized for use on all 9.7" iPads running iOS 8 or higher. Opto will run on non-retina display iPads and the 9.7" iPad Pro. However, the anaglyph (red/cyan) activities, however, may not cancel as well as they do on retina displays.
is opto intended for use in the clinic or for home practice?
Both! While Opto is specifically designed for use only under the guidance of a vision care professional, built in features allow patients to easily use Opto at home for practice between clinic visits. Learn more about setting up a personalized practice routine in our About Opto video.
