Red/Cyan Arrows

Developed exclusively for Opto. Available now for iPad! 


This exercise features directional arrows at a variety of 3D levels. The number of arrows progressively increases as you move from one image to the next. You can also use "dynamic mode" to alter the vergence demand of a single arrow using a slider control. Supression controls are included on every screen.

Required hardware: red/cyan glasses (available here)

How to Purchase: Available as an in-app purchase in Opto, the vision training app for iPad. Download Opto and find Red/Cyan Arrows in the in-app library of exercises. Available as an individual exercise ($4.99 USD) or at a discounted rate in Expansion Bundle 2 ($69.99 USD).


Interactive mode: View the images one at a time. Use forward and back arrows to navigate between the 6 available images. Each image contains targets in various 3D levels, as well as suppression controls.

Dynamic mode: The fusion demand of the main target is controlled by a slider. You may also tap and hold the image to drag it to any area on the screen. Suppression controls also displayed.



Like all activities in Opto, a report is generated including the date and duration of the exercise. A patient assessment is also recorded if the user is signed into his/her personal profile.
