As virtual reality technology grows and develops, small problems will arise. One long-standing problem dating back to 2014 and appearing in Daydream, Gear VR, and even Oculus Rift is that one eye appears darker on screen than the other.
What makes one eye darker than the other?
When one eye sees content that is darker than the other, you see a display problem. There is no exact cause, although there are a few things you can do to try and prevent this issue from occurring while playing in VR.
Basically, when the game is coded, the darkness level is given for a dark background. This level starts with one that is quite dark and goes up from there. When a game is encoded with a higher darkness level, your headset has to work harder to display it correctly. Although this is an annoying problem, you cannot deal with it. There is one fix though.
Some Gear VR users have reported that you can fix this problem by lowering the brightness of the headset. This means that your headset — or, in some cases, your phone — doesn’t have to work so hard to display the virtual game you’re trying to play.
