Hi sonicfox,
Yes, Sony and others make goggles that fit over eyeglasses and they are mostly clumsy, heavy and uncomfortable (I wear eyeglasses).
I hate them. Most people who wear eyeglasses, like me, dislike wearing them, and to ask people to don a second pair is ridiculous. (I can't wear contacts.)
Other than gaming, which is huge, of course, I do not think 3D has much of a commercial future so long as the 3D googles are required. Besides, there are all kinds of annoying motion anomalies in 3D whenever a camera pans and with fast action. I even watched a World Cup soccer in 3D demo at a press event in New York last week and it didn't add much, except for the goalie camera shot, with the net in the foreground.
It's a novelty, and I think it will pass, just like it did in the 1950s. Of course, never underestimate the marketing and hype engine. . .if you tell enough people and a lot of dumb press people that something is great, and advertise it everywhere, people will come to believe it. Look at Bose.
Cheers,
Alan
