Diplopia, the VR Game to Help Strabismus

Diplopia is a game designed using the latest research to help amblyopia (lazy eye) as well as strabismus (crossed eye) in stereoscopic virtual reality using an Oculus Rift hrad mounted display.

How James Blaha's Diplopia game helped him see in 3D

James had been following this neuroplasticity research and decided to start a virtual reality, side project with the Oculus Rift to put some of these studies into practice. He created some scenes that increased the intensity to his lazy eye and decreased the intensity to his good eye, and he was blown away at being able to see in 3D for the first time in his life.

Encouraged with his success, he continued to develop a series of games that he played for over 20 hours over the course of 3 weeks until he was able to see in 3D in the real world for the first time in his life. Watch the video here under to learn more.

A successful Indiegogo Campaign

The crowdfunding campaign on Indiegogo ended with over 1000% of the initial $2,000 funding raised in January 2014.

Strabismus, better known as crossed eye, is present in about 4% of children. In those affected both eyes do not line up properly causing diplopia (double vision), amblyopia (lazy eye), and loss of vision in one or both eyes. Since the brain receives conflicting information from the two eyes it often learns to disregard the weaker of the two, suppressing it.

This leads to a loss of depth perception and stereoscopic 3D vision. It was long thought that once a person's brain had learned to suppress one of their eyes that they could only unlearn this suppression before a "critical age" of between 8 and 12 years old. Only recently has it been shown that certain kinds of therapies (including video games) can actually treat amblyopia past adolescence, allowing for the possibility of restoring 3D vision in adults.


Diplopia takes advantage of the wealth of new information in scientific studies that have come out in the past couple of years to create an experience that will hopefully help people who have a suppressed eye to use that eye in conjunction with their good one. Whether you have amblyopia or not, Diplopia is a game that is fun and challenging to play for everyone. All eye-training modes, Oculus Rift support, and Leap Motion control will be totally optional.
