I bought some fake Ray Bans. Are they safe?

I want to know if my fake Ray Bans are safe. I bought them at Chinatown, and it had a "100% UV Protection" Sticker on it. Does that mean it blocks UV?

Unfortunately most of the time fake brand-name sunglasses are not safe. Even thought they have a sticker on saying that they offer 100% UV protection.

The good news is that you can still wear them while driving. The windshield won't allow UV light through. I would recommend you to get a pair of authentic Ray Ban sunglasses that you can wear when you are planning to spend a lot of time outdoors.

Just wanted to comment on the fake Ray-Bans: You can actually be putting your eyes in more danger weraing cheap sunglasses than if you were wearing no sunglasses at all! When you wear a cheap pait of sunglasses, that tint in the lens block out some visible light, and your pupils will open up to compensate, letting more light through, and if the glasses don't block UV, then more UV gets into your eyes then if you wore no sunglasses at all! So you can actually be doing damage to your eyes.

Unfortunately, anyone can put a 100% UV sticker on a pair of sunglasses, and there isn't any practical way to tell whether it is true. The only thing you can do is buy eyewear from a manufacturer you trust.
