Polarized Lens: It Is Useful?

Using sunglasses is not just to make you look good, sunglasses actually have wonderful health benefits, especially for your eyes. According to experts, the best kinds of sunglasses are those with polarized lens.

Effectively Reduces Glare

Polarized lenses effectively block out light rays which would normally enter your eyes. The rays of the sun reflect light in almost every direction, so whenever a ray hits a flat surface, the reflected light will shine back at your eyes and is magnified causing glare. Glare can be a huge problem because it can cause a myriad of visual problems like distortion, change in color perception, and may sometimes even cause temporary blindness.

Regular sunglasses are made to reduce a small amount of light which is transmitted through the lens either vertically or horizontally. Using polarized lenses, the sunglasses absorb horizontal light ways and lets vertical light waves to pass through. Since only light that travels in one direction is allowed, glare is eliminated effectively with polarized lenses.

Reduce Eyestrain

Eyestrain is another common and nasty side effect of glare and harmful UV rays of the sun. Using polarized lenses will reduce eyestrain for good. When you squint to try to see better, you are putting stress on your eyes. This creates discomfort which causes several problems including redness, irritation, headaches, and fatigue. Polarized lenses effectively neutralize this problem allowing your eyes to feel more relaxed and comfortable.

Provides Better Vision

When you opt to use polarized lenses, you will be able to see colors better and clearly. The images are unlike anything you have experienced before because our eyes are more relaxed to focus even on the harshest days. This is the same reason why polarization is best when you are engaged in outdoor sports. You will be able to see clearly even during times like downhill skiing, snowboarding, flying a plane, or other outdoor activity.

Best For Water Sports

Many fishermen, boaters, surfers, or other water sports enthusiasts’ loves polarized lenses. Polarization is a material which lets you clearly see even when there is a reflection from the water. Without these polarized lenses, the surface of the water will simply reflect everything around it to your eyes, making it difficult to see clearly.

Tinted Lens Versus Polarized Lens

Tinted lenses are good for reducing brightness. It may work for you during an ordinary sunny day. However, they do not eliminate glare like polarized lenses do. Remember darker lenses do not necessarily mean better protection against the harmful UV rays of the sun.  The best that you can do is to check the level of protection the lenses provide.

Polarization is a special material which is every effective in reducing glare. If you are looking for sunwear this will be your best choice if you plan to spend a lot of time outdoors.
