Traits of Good Sunglasses

Eye problems are growing throughout the world due to the increasing amount of ultraviolet (UV) radiation that is reaching the atmosphere due to global warming. Eye specialists are recommending that people wear sunglasses to safeguard their eyes from harmful UV rays. Overexposure to UV rays can cause eye problems ranging from eye irritation to cataracts and even skin cancer.

It is very important to choose the sunglasses with lenses capable of blocking UV radiation effectively. (Remember, not all sunglasses block UV rays.)

Here are some of the most important features of good sunglasses to help you pick the right pair:

UV protection

A pair of high quality sunglasses will have UV protection details on its product label. There are different types of UV radiation, so let’s pause for a moment and consider what this means. UVB rays are the main concern for eyes. According to the American Academy of Ophthalmology, “Long-term exposure to UV radiation in sunlight is linked to eye disease. UVB radiation is considered more dangerous to eyes and skin than UVA radiation.” UVA rays are the primary ones absorbed by your eyes. While they pose far less concern than UVB, doctors still recommend that they be avoided.

High quality sunglasses should block 99 to 100 percent of both UVA and UVB rays. Examine the UV protection details carefully to make sure you are getting the level of protection you desire and to avoid unnecessary regrets later.

Quality of lenses

There are different types of sunglass lenses with a wide range of functionality:

Blue-blocking lenses may provide extra protection to people with blue or light-colored eyes who may be particularly susceptible to macular damage by blue light.

Polarized lenses filter certain horizontal light waves, substantially reducing blinding glare and the resulting eyestrain.

Photochromic lenses automatically darken or lighten according to changing light intensities to protect your eyes in a wide range of conditions.

Polycarbonate lenses are impact-resistance and lightweight, with very good optical clarity.

Mirror-coated lenses can be great for many activities. Various coatings can repel water or resist scratches and fog

Each type of lens has its own unique functionality and capabilities. Hence it is important to check out the best sunglass lens for your needs to make sure you have the best possible visual clarity and comfort.

Frame design

Frames are almost as important as lenses. A tiny frame may not be able to protect the eye from UV rays entering from above and sideways. However, frames that are too large may be heavy and uncomfortable. Good quality sunglasses will have proper frames and lenses to offer complete protection, style, and comfort.
