Like any eyewear, different sunglasses offer different coatings that can dramatically change the way 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-reflective
A common coating on eyeglasses, a Anti-reflective coating Reduces the amount of light that reflects off the glasses on both sides of the lens. This increases the overall light transmission of your lenses, which is especially important for prescription lenses. This coating may reduce some ambient glare (water reflections), but the main goal is to improve light transmission and reduce glare from the lenses themselves.
Polarized lenses
You will see polarized lenses There are many sunglasses designed for different sports, but they are a great option for anyone who spends a lot of time in the sun (or snow!). Polarized lenses filter light in such a way that they dramatically reduce or eliminate the appearance of bright light reflecting off almost 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 darker than you might expect. However, they make electronic displays look quite strange.
Preventing this light from entering your eyes helps protect them in these bright environments, but polarized lenses do. No They automatically provide protection from ultraviolet light, so be sure to look for a label that still includes UV protection. However, every pair of polarized lenses on this list provides both layers of protection.
UV protection
Sunglasses should protect your eyes from more than just bright light, they should also protect them from ultraviolet light. UV exposure is generally something to avoid and protect against, as it contributes to long-term vision problems including cataracts and some eye cancers. He American Academy of Ophthalmology highly recommends UV protection for your eyes.
With the right coating or materials, they can provide almost complete protection against UV light. Polycarbonate lenses offer protection against ultraviolet light without an additional coating, but you should always look for a sticker that says “100 percent UV protection” or UV400 protection, to confirm that your sunglasses have been tested for UV protection factor. sun. All sunglasses on this list provide 100 percent UV protection.
