Seems like there are issues with the Oakleys vs. more basic ones. Oakley Gascan 3D Glasses Review
They curve the lens which impacts focusing ability, they are also heavy on the bridge of your nose meaning that you feel that they are there more, and the lenses are smaller that the "ugly" ones, meaning that you never get fully immersed into the image.
Not that they are terrible, but just some of the trade-offs to get stylish glasses with a brand stamped on them that you will be only wearing in a dark room where nobody will really see them.
