Can't wear my glasses under my mask, and when I tried to have contacts fitted, it was hellish (nearly punched the guy when he tried to put them in!).
At the moment I am okay without the glasses, but any suggestions on a way round this - does anyone do prescription mask lenses?
With ski goggles I have seen people simply cut a gap in the sponge/foam for the arms of the glasses to go through. Seems to work for them. Might work on paintball masks
Try vforce masks, I wear glasses and have had no problems with either the profiler (oldish mask) and the grill, couldn't get of with dye i3's, my glasses rubbed on the lens of the mask, not sure about the I4 as I never tried them.
