> Having a screen blast your eyes 2” away is only ok for so long.
Distance isn't really a factor here, at least not as far as total light entering your eyes goes - a 1W/m^2 source 10cm from your eyes causes the same amount of light to enter as a 16W/m^2 source 40cm away.
What matters, as others have pointed out, is the distance between your eyes and the focal plane.
