One of the most important things that you can do for your eyes is to protect them from exposure to the sun. In order to do this, you should know the different types of sunglasses lenses and understand the difference. This will allow you to make the best choice for you when deciding on a pair of sunglasses. We all love to have a little fun in the sun. Many times, though, we don’t stop to think how extended exposure to the sun affects us. One of the most sensitive areas of our bodies, and one of the most important, is the eyes. If you like to play in the sun, or if you work in the sun, you should be sure that your eyes are protected.
Different types of sunglasses lenses offer different degrees of protection. Regular lenses offer the lease protection, while polarized lenses offer more protection. Regular sunglasses are uniformly tinted, which means that the lens does cut down on the amount of light that reaches the eyes. However, polarized lenses are tinted in tiny, parallel lines. The rays of the sun bounce off of surfaces in waves. For instance, once the sun’s rays hit the hood of your vehicle, they bounce off in waves that are reflected by polarized lenses. Regular lenses only limit the amount of light that reaches your eye, and cannot deflect the glare that occurs once sunlight hits a surface.
Other types of sunglasses lenses include anti-reflection coating and panchromatic lenses. Panchromatic lenses increase in darkness as more light hits them, protecting your eyes from the brightest light. Anti-reflective coating is an application containing metal oxides that is applied in layers to the front and back of the sunglasses lenses. These layers are designed to block reflected light. When reflected light is block, this reduces the amount of glare, reflections, and halos that surround bright lights.
No matter which type of sunglasses lenses you choose, the most important thing is UV protection. When choosing sunglasses, you should choose sunglasses that provide 100% UV protection. UV light is the light that the sun puts off. This light travels to Earth in wavelengths. If you plan to spend extended periods of the time in the sun, it is very important to protect your sensitive eyes from the UV rays. Without protection, the only thing you have to lose is your eyesight. And, that is something that you want to protect!
