Another type of harmful ray emitted by the sun are infrared rays, which are heat rays. If you’re exposed to sunlight for an extended period of time, such as a day spent at the beach, without infrared protections, you may begin to experience a burning or stinging sensation in your eyes or a sense of fatigue. Infrared rays can be especially discomforting for contact lens wearers. If your sunglasses fail to block the infrared light, it can be absorbed by your contacts causing them to "warm up".
Studies have shown that most people exposed to normal amounts of infrared light are not at risk, though there are some people who are exposed to higher amounts, and these people need to be careful and protect both their skin and eyes from these damaging rays. People who are at a greater risk for infrared light damage are those who live or work at higher altitudes. Pilots must take special precautions to protect against infrared light exposure, as well as mountain climbers, skiers, or those living at higher altitudes.
Grey and green lenses generally offer the best protection from the infrared rays emitted by the sun.
For a super sporty style of lenses that will effectively block infrared rays for days spent skiing or mountain climbing, try style A8-PC1643_SPORTS inspired by Komodo. These replica sunglasses will not only offer 100% UV protection, but they also offer extra protection from infrared rays with gray lenses. For under $30, these discount designer sunglasses are a steal!
