I've never gotten goggles to work with glasses; they always fogged up, even when moving. Until I got contacts, I used to just ski without glasses. I did work with a ski patroller in Tahoe who wore Smith Turbo goggles, which have an internal fan, over his glasses and he said that they worked pretty well. They didn't fog up while he was moving, at least.

When it gets wicked cold, I ride with my ski goggles. Very warm and comfy, and highly recommended. But if you don't wear contacts, it'd probably be best to find goggles that allow for a prescription lens, like the kind that AllenG mentions above.
