Why is it important to purchase special sunglasses for ski?

If under warranty and you have receipt, it should be ok for replacement/repair. Without that the retailer can make life a bit difficult. P O purchase is very important.

Hi Karen,
there are a number of places that specialize in replacing scratched or broken sunglass lenses.
www.thesunglassfix.com is probably the largest out there and known for good quality at a great price. However, there are others like fuse.com and your local optomentrist that may have the lenses.
Most offer the option of having the lenses sent out to you or you sending in the frames to get new lenses.

Have tried many of the "buffing out scenarios above" and my personal opinion is they don't work and only make matters worse. Getting new lenses can cost as little as 10% of the purchase price and complete resolves the issue for years.
Good luck Craig

Kids tend to spend a lot of time in outdoor activities and that is why it is extremely important to pick high quality sunglass.sunglasses that block 100 percent of the sun's harmful ultraviolet (UV) rays are extra important for children.In fact, many experts believe our eyes get 80 percent of their total lifetime exposure to the sun's UV rays by age 18. And since excessive lifetime exposure to UV radiation has been linked to the development of cataracts and other eye problems, it's never too early for kids to begin wearing good quality sunglasses outdoors.

Sports sunglass design is a competitive sector in the eyewear industry. There are many companies competing to produce the best design, highest performance sports sunglasses. When it comes to the best labels in the industry, Oakley and Ray Ban are top-of-the-line designer labels offering extremely effective sports sunglasses. Other companies you may want to consider include Lacoste, Puma and Nike.
Its best to look through a number of models before making a final decision. Sometimes ultimate effectiveness may require purchasing more than one model, depending on how many sports you're interested in. Choosing an effective pair of sunglasses is almost as important as whether or not you win the game almost as important, but not quite.

Here are some important features: 1.Competivision is a term created by Bolle Eyewear, one of the best manufacturers of sports sunglasses.

This is a must-have feature for all tennis players. 2.Polycarbonate Lenses-Tennis sunglasses, like other types of sports sunglasses, require polycarbonate lenses for impact and scratch resistance. Tennis players need these types of lenses more for impact and shatter resistance than anything else. 3.Polarized Lenses-Polarized lenses are extremely important in most sports - tennis is no exception.

Glare from the rackets, the net or the court can hinder your performance so its important to choose sunglasses with polarized lenses. 4.Tight-Fitting-You're going to want to choose a pair of sunglasses that fit snug to your face. A huge part of your performance as a tennis player is agility. You can't stop between every hit to stabilize your sunglasses or pick them up if theyve fallen off. You need a pair that's going to move with you, fitting tight and comfortably on your face.
5. UV Protection-UV protection is a very important element in any outdoor sport. It's not enough to simply have UV protection anymore, you have to make sure the sunglasses you choose provide 100 percent UVA, UVB and UVC protection.
