From here.Additionally, my glasses prevented the Rift from fitting perfectly snug against the front of my face, creating a binocular-esque circular black border around the edge of the display that glassesless folk have told me they did not experience. This made adjusting the Rift until its displays were at the correct viewing angle more difficult than it seemed like it should have been, or at least more difficult than I would have preferred.
So although the Rift works with glasses, you probably won't get the optimal experience while wearing them. The line was too long the last couple days so I didn't get to try it again. It may be possible to use it without glasses if you are nearsighted. It may also be possible to have lenses made for the OR that are corrective, but that will probably be prohibitively expensive.
I'm a little disappointed but not at all surprised there is some limitations associated with using the OR with glasses. Just another reason for me to get Lasik...
