Clinical research is proving that amblyopia (lazy eye) is treatable. Try now this vision therapy process, with which each eye sees a separate image.

Practicing the lazy eye exercises has shown significant results for:
‣ Improving visual acuity of the lazy eye
‣ Improving the binocular and stereoscopic vision

Studies were usually conducted over a period of 5 weeks, playing the games 1 hour a day.

All you need is the Duovision app and a pair of 3D glasses (anaglyph glasses, with red and cyan lenses, usually less than $5 on internet).

Features :
‣ Play some games using the dichoptic vision process
‣ Adjust the difficulty level of the game
‣ Easily calibrate the colors to suit your anaglyph glasses and screen
‣ Create reminders to think about playing
‣Track your performance by game statistics and game time

This app can be used by :
‣ those with no visual problem
‣ those with functional amblyopia, resulting from anisometropia (strong difference in visual acuity between the two eyes) or an already corrected strabismus.

Lazy eye (amblyopia) is a pathology that prevents or deteriorates vision in 3D (impact on depth and distance perception). The pathology blocks in various degrees the signal sent by the ambliopic eye.
WARNING : Therefore, people with uncorrected strabismus may face a risk of double vision (diplopia) using this application. We recommend in this case to not use the application. If you have any doubt, consult an ophtalmologist.

Crashes when calibrating colour

As the title suggests, the app crashes every time I click on “calibrate colour”, so I am unable to set the colours correctly. Please fix!
