Sport sunglasses are really about two things, performance and eye health. Regardless of whether you are actively involved in a sport it’s recommended that you invest in a pair of high quality sunglasses as such to protect your eyes from the potential for UV damage. Any time you’re out in the sun, your eyes are exposed to UVA and UVB rays, each of which can deteriorate your eyesight and eventually lead to cataracts.You will find a wide array of protective eyewear that offer UVA ray protection from the sun. However, UVB rays from the sun are also highly damaging. You will need to find sunglasses that give you protection from both of these rays while giving you the prime conditions for fine tuning your visual needs.Water and snow reflect the sun’s rays right back to your eyes. This not only can cause eye health issues but it is also likely to cause glare problems. Glare from reflected sun can cause performance problems that lead to serious accidents and injury regardless of the sport you engage in.Let’s not forget that good eyewear is going to protect the eye’s skin as well. While wrinkles are not always on the top of our list of preventative maintenance, going without quality glasses can contribute to the development and worsening of crow’s feet and eye wrinkles.Distortion through low end Sport Sunglasses can be problematic as well. When you put on a pair of sunglasses, the image that you focus on should look basically the same as it is without sunglasses. You shouldn’t see it get bigger, smaller, or move to the left or the right. You can ensure that the sight through the eyewear will remain the same by buying lenses that have been classified as distortion free.Few of us who are new to buying protective eyewear have heard of VLT, or volume of light transmission. It is important to peg the range of VLT somewhere in the vicinity of 18 to 27% in order to ensure that you have good viewing terms through the lenses without the risk of harmful sun effects.Sport Sunglasses can change the way you are able to perform whether you’re windsurfing through the summer time, snowboarding through the winter time, or biking all year long. Whatever your sport, eye protection is essential for performing at your best while preventing eye problems that can sideline you in the future.
