I'm nearsighted and wear glasses, and frankly didn't even think it'd be an issue focusing on a screen 2 inches from my eyes, but I didn't account for the way they calibrated the focal distance. My glasses don't fit, and frankly it's kind of painful trying to focus while wearing the Rift. I know a 3rd party is trying to set up a business to create some clip on lenses to fix this, but I'm just incredibly disappointed with Occulus for not including some means of focusing the eye pieces. Just a warning to anyone who wears glasses and thought they could get away without using them, you probably aren't going to be able to. Definitely try it before dropping so much money on one of these.
