These are nice and lightweight sunglasses that fit over my prescription eyeglasses. They are size large, at least that's the size of the ones I received, which is the size that I wanted. The frame is transluscent but dark, the frame also blocks the UV rays and sun glare as the lenses do. I like the fact that in addition to providing UV protection and glare protection from the sun, the wide legs and curved-in top, and the size of the lenses themselves all combine to block a lot of wind and dust from getting into my eyes and irritating them, especially from the side. I certainly would buy another pair or more than one pair, as they come in various colors and even in clear. Mine came with a pouch. The price is affordable and they do the job. Don't expect luxury, (remember the price,) instead, expect effectiveness. This company makes lenses that are polarized and non-polarized. Do yourself a favor and buy the polarized, even though they are more expensive, you will be able to see much better with polarized lenses, regardless of the brand.

This is an update, I am writing this in November, 2012: The absolute BEST fit over sunglasses are Cocoons brand, and the best lens color is COPPER. The copper-colored Cocoons brand lenses and frames are MUCH, MUCH better than these. It's amazing how crisp and bright one sees with the Coccon copper lenses! There is no comparison. Every aspect of Cocoons is far superior to anything that I've seen out there in the marketplace. Needless to say, Cocoons is a lot more expensive than the other brand. If I remember correctly I paid $49.95 for the Cocoons when I bought them several months ago. I even bought a second pair because I liked them so much. I bought size Pilot, they fit well over my prescription glasses with room to spare; Their largest size is Aviator, those are enormous, I don't think most people would need such a big size, unless their prescription glasses are unusually wide. Do yourself a favor and go to the Cocoons website and read about them before you decide what to buy.
