Amblyopia is a condition in which a person's eye and brain are out of sync and if left untreated, people with the condition can go blind in one eye. It is reported to affect three percent of the global population. Amblyotech chief executive Joseph Koziak said, "Amblyopia involves one eye being far less useful than the other, creating a situation in which the brain responds by suppressing visual input from a weak eye and relying on the strong eye. Relying on one eye results in people losing depth perception. When you look at a person who has it, one eye is visually misaligned as compared to the other. The traditional monicker is 'lazy eye'."
The game requires both eyes to take part in order to effectively play the game. Characters, equipment and scenes set on a gray background are either red or blue, and players have to wear glasses that filter out one color or the other depending on the eye. Ubisoft senior producer Mathieu Ferland said, "The only way to play this game is to force the patient to use two eyes. This treatment is reconditioning the brain to use both eyes. This is a good demonstration of the positive impact that video game technology can have on our society."
Pricing for the game is yet to be announced. Amblyotech is seeking approval from US health regulators to have 'Dig Rush' be prescribed by doctors.
