I too need to wear glasses for reading and was worried about having to use them with the Rift but have been pleasantly surprised to find I get a perfectly focused image without them. As for motion sickness, it was a big deal at first and just turning left or right in a game while moving would have me needing to remove the headset. And barrel rolling in Eve Valkyrie! Forget it!
Just spent a while turning left and right in Eve and barrel rolling galore. No motion sickness. I'm finally able to play the game in non-scout mode (: So for new Rifter's experiencing VR sickness you definitely develop a tolerance to it with use.
Even gotton over my vertigo in the city scape Dreamdeck demo but, to be honest, I'm actually a little disappointed about that. Everyone I've demoed the Rift to agrees that, while the T-Rex demo is great, the city scape scene gives you a real taste of what VR can do.
