All You Need To Know About Pit Viper Sunglasses

Benefits of Sunglasses

A pair of good sunglasses protects the eyes from the sun and other harmful ultraviolet rays. Good sunglasses will also block 97% of the UVA and UVB rays. In order for a subclass to do this, it needs to have polarized lenses.

Sunglasses polarized light rays will also help protect your eyes from UV rays. The sun's UV rays can damage collagen, causing dry, painful eyes. The best sunglasses to block UV rays are those that have a high index, meaning the lens has a high index of reflection, which greatly increases its effectiveness in reducing reflected glare. This is different from an anti-reflective lens, which has less of a high index. Anti-reflective lenses can sometimes contribute to more concentrated reflected glare, but their greatest effect is the reduction of all reflected light rays. These are the best pair of sunglasses to use when going for an outdoor activity.

Advantages of Polarized Sunglasses

Polarized sunglasses reduce glare by correcting the spherical aberration in human eyes caused by refractive errors in the lenses. This distortion is what causes our eyes to image things upside down or to appear distorted. Polarized lenses don't allow the sun's rays to shine through, which improves our eyes' performance outdoors. Another advantage is that they will increase your vision by a factor of ten, because they focus the sunlight that do come through. This is because the polarized filter reduces the scattered light and allows the rays to enter the lens directly.

Polarized sunglasses are also great for blocking out high intensity sunlight. This is particularly important during the summer months, when high intensity sunlight can cause damage to the eyes through thermal shock. The best sunglasses to block out UV radiation are the ones that have at least 99% coverage in the Ultraviolet or UVA category. However, even if you find the highest rated product, you should still check the label to make sure that it blocks out UVA and not just the UVB rays. All sunglasses have a certain level of UVB that they can block out, but those that are rated high are also rated high in UVA.

Pit Viper Polarized Sunglasses

If the eye gets too much UV radiation, it automatically closes the pupil. The second step is squinting when there's too much light as there could be if sunlight is reflected off of snow.Polarized lenses reduce glare by making the field of view larger than the unaided human eye. Good sunglasses will eliminate UV rays entirely. For example, Pit Viper the Cosmos blocks 99% UV RAYS. 

Since the UV ray won't reach everyone's eyes, a pair of good sunglasses should be worn in all conditions. Even when it's sunny, children, the elderly, and people with certain allergies should go outside. If the neighborhood has lots of kids, everyone should wear shades. Anyone with a severe allergy should stay indoors. Just like indoor weather, the air outdoors is more polluted than indoors.

Two Types of Lenses

There are two types of lenses in good sunglasses - gas permeable and anti-reflective. The first has lenses that are coated with gas to reduce glare. The second type has lenses that are coated with anti-reflective materials to reduce glare. Both types work to minimize the bright reflection off of nearby objects. Manufacturers provide instructions for the best choices of lens for each situation.

Three Components of Visual Acuity Rating

There are three components to the visual acuity rating: peripheral vision, central vision, and the ability to focus. All sunglasses should have at least a high peripheral vision rating, because peripheral vision is what lets you see the entire area that you are looking at. The best ones will also have high levels of both the peripheral and central vision. The best sunglasses to use for these conditions are ones that have high levels of the ability to focus while you are looking at the sun. They will not only block out the UV rays, but they will also cut out the glare so that you are able to see the entire area without having to squint or turn your head.
