just for your information. there is only little knowledge about the influence of vr glasses on the vision. there have been reports of developers that worked in vr for a long time that had issues with theyr sight afterwards.

problems can come from increased heat within the vr device, but also because every lighty our eye receives comes in at the same angle, and thus the eye never needs to adjust to different distances, as it would have to do in a real environment. while it appears / looks the same as in reality it really isnt. thats also the reason you only need one correction.
