There are many reasons why people like to use polarized sunglasses. The first and most obvious reason is that the polarized lens reduces or eliminates eye strain and discomfort caused by polarized contact lenses. It also makes it easier to see at night. Polarized sunglasses are especially useful for regulating glare. Polarized sunglasses are what occurs when the light entering your eye is refracted back at an even higher magnitude than the normal glare and that means that while your normal eyes are blocked by the glare, they are still shielded from the main direct reflective glare.
good peripheral vision because the reflected glare is in focus
The second major benefit is that these lenses make it much easier to have good peripheral vision because the reflected glare is in focus. Most sunglasses offer some peripheral vision relief but as soon as the object to be focused is far away from the reflected glare ends up being blurred. With polarised lenses, this is not the case. As the intensity of the incoming light is reduced, more of it is in focus and as a result, you get better peripheral vision.
block more of the harmful UV or ultraviolet (UV) rays
The third reason why people like polarised sunglasses is because they block more of the harmful UV or ultraviolet (UV) rays than ordinary sunglasses do. Most people are exposed to very high levels of UV rays without even noticing it. The average sunlight is usually enough to trigger hyperpigmentation of the skin which is the main cause of wrinkles. Polarized lenses help to reduce the number of UV rays entering the eye and this prevents early signs of aging such as wrinkles and age spots.
Sunglasses block up to 90% of UV rays
The fourth reason is that they provide more protection from UV rays. Sunglasses block up to 90% of UV rays and polarized lenses allow just a fraction to pass through. In other words, if you use a pair of polarized sunglasses on a sunny day, you will almost certainly avoid the sunburn that normally occurs when basking under the sun. However, a polarised lens alone cannot block all UV rays. If you want complete UV protection, you have to add a layer of silicone gel or some other kind of UV blocking lens onto the surface of the lens. The benefits of polarised lenses, therefore, extend well beyond UV protection.
improve eye health
The fifth reason why people enjoy using these sunglasses is that they improve eye health. One of the biggest causes of eye health problems is inadequate sleep and lack of physical activity. Polarised lenses help to alleviate these conditions because they reduce the amount of light reflected from the retina. As a result, the eye’s natural contrast and color accuracy are enhanced, which leads to better eye health. In addition to improving eye health, these sunglasses are stylish and can be used by people of all ages and professions.
exposure to the harmful ultraviolet rays without any form of protection can lead to serious eye damage
If you often spend time outside without wearing protective eyewear such as sunglasses, you may already realize the many benefits that they provide. If you don’t spend enough time outdoors, it’s also important to remember that prolonged exposure to the harmful ultraviolet rays without any form of protection can lead to serious eye damage and even blindness. Polarised sunglasses are an excellent solution for both of these conditions and many other common problems caused by sunlight.
