Like any type of eyewear, different sunglasses offer different coatings that can dramatically change how they protect your eyes and how you perceive the world around you. Below is a breakdown of some of the most common types of coatings and how they work.
Anti-reflection
A common coating on eyeglasses, one anti-reflective coating reduces the amount of light reflected from your glasses on both sides of the lenses. This increases the overall light transmission of the lenses, which is especially important for prescription lenses. This coating can reduce some environmental glare (underwater reflections), but the main purpose is to improve light transmission and reduce lens glare.
Polarized lenses
You will see Polarized lenses There are plenty of sunglasses designed for different sports, but they’re a great choice for those who spend a lot of time out in the sun (or in the snow!). Polarized lenses filter light in a way that greatly reduces or eliminates the appearance of bright light reflected on any shiny surface (such as water, ice, snow, glass, or metal). Through polarized lenses, the world around you looks a little sharper and a little blurrier than you might expect. However, they make electronic displays look quite strange.
Blocking this light from entering your eyes will help protect them in these very bright environments, but polarized lenses do. Are not automatically provides protection against UV rays, so make sure you look for labels that still list UV protection. However, every pair of polarized lenses on this list offers both layers of protection.
Anti-ultraviolet rays
Sunglasses not only protect your eyes from glare but also protect them from ultraviolet rays. UV exposure is generally just something to avoid and protect against, as it contributes to long-term vision problems including cataracts and some eye cancers. The American Academy of Ophthalmology UV protection is especially recommended for your eyes.
With the right coating or material, they can provide almost complete protection from UV rays. Polycarbonate lenses provide UV protection without the need for additional coatings, but you should always look for a sticker that says “100 percent UV protection” or UV400 protection to confirm that the UV protection factor is Your sunglasses’ ultraviolet rays have been tested. All of the sunglasses on this list offer 100% UV protection.
