Tiger Woods! Tiger Woods again! Champion again! People maybe don't remember the day that he won a big game when he was a teenager. But most of the people do remember that he has won dozens of champions in the world. And in the world of golf, Tiger Woods is a legend; his name is like a myth. Last month, when he met his fans, wearing a pair of sun glasses with color lenses, a lot of girls even screamed to tears, many of them wanted to give him a hug. But be careful young ladies, Tiger sometimes is really a tiger.

Like I said at the last paragraph, I notice that Tiger Woods were wearing a pair of sunglasses with color lenses. It seems like more and more color lenses are being used. First of all, there is no doubt that it is cool to wear a pair of glasses with color lenses. These lenses can change colors. That makes people's face more gorgeous and more colorful. But the most importantly is: it could prevent hard light and ultraviolet rays perfectly. Its principle is that the material of the lenses consists of silver halides. So when they meet the hard light or ultraviolet the lenses could change colors and absorb them. But back to the places where there is just normal light, the lenses can get transparent again. Isn't it amazing?

As a matter of fact, what I said before just provide something we could take advantages of. We can use the color lenses to make glasses for myopia. This kind of glasses not only can prevent people from short eye sight but also can be used as sunglasses. When you are inside this is just a pair of glasses for myopia. It is no differences from other glasses. But when you walk outside, it becomes the sunglasses. There is no need to add extra sun lenses on your glasses.

I have got a pair of glasses like this. When it meets sunshine, it could turn brown. I bought it on the website: www.glassespeople.com. This website is good comparing with other websites which sale prescription sunglasses and eye glasses. You can choose whatever kind of glasses with color lenses. Like you can choose the color that it turns. By the way, if you are a person who is short-sighted, the color lenses which are light red are more suit you.
