The tests were conducted with the Oculus Rift OC DK2 goggles and software developed by Vivid Vision, using the Diplopia Game.
The studied subjects played for 8 sessions (two per week) for 40 minutes, two different games (20 minutes per game): one in which they flew with a spaceship and another with blocks. Both were presented in a dichoptic configuration (a different image for each eye).
For example, in the space game, asteroids and gates were shown to the amblyopic eye. At the same time, the spacecraft was visible only to the other eye to avoid cheating and thus force the use of both eyes to successfully achieve the game’s purpose.
During the trial, the participants underwent no other visual training (10 were treated with patching during their childhood).
