Why single out video games in particular? If there is a problem, the problem is the screen. Or rather, how close it is. It is unlikely to be related to the content.
I wouldn't be surprised to learn about a feedback loop getting disrupted. For many organs in the body, an approximate shape will work just fine, who cares if an organ is slightly off by a few millimeters. Not so for the eyes.
