I read the Rift is actually the worst for bespectacled people, with the least amount of room inside the goggles to fit eyewear. If your frames are too wide they'll stick inside the Rift and you'll have to take off your glasses and put them inside the Rift before putting the gogs on your face...
Also, since both the rift and vive rest some (most?) of their weight on your nose, you end up with the nose pads of your glasses squishing into your nose = total fail as far as comfort is concerned. PSVR is superior here as it rests its weight mainly on your forehead, and it has the most room inside of it for your frames as well, allegedly.
This according to... Uh, I can't recall where I read this right now, sorry. Some post on Kotaku?
The Rift supports changeable face plates specifically to accommodate different types of glasses. Unfortunately the launch bundle only comes with the default one though so presumably you'll have to purchase the the different ones when they release.
