Sunglasses with several special functions

Sunglasses with several special functions

Sunglasses can be divided into several types according to their functions. For example, the common ones are polarizers, photochromic sunglasses, mirror   sunglasses, etc. What is the difference between these types of sunglasses and ordinary sunglasses? What are the special features of the functions?

Polarizer

Polarized lenses reduce glare and are used on level roads, water, ice, and snow. Can be worn while driving, skiing, water skiing, cycling. For patients after   cataract surgery and the elderly who are sensitive to light, choosing polarized sunglasses for these groups can also improve visual comfort. In addition, driving with polarizers will have a wider view, but you may not be able to see digital displays such as LED displays, GPS and mobile phone screens in the car clearly. Color   recommendation: yellow, brown, blue, can filter blue light.

Polarized sunglasses cannot be used for flying. For some sports, such as golfing, polarized sunglasses may cause some loss of visual information, affecting   performance.

Photochromic mirror

Color-changing glasses are usually sensitive to ultraviolet light, and the color of the lens becomes darker or lighter as the light intensity changes.

For people who wear   glasses themselves, photochromic mirrors are more convenient, and they are more comfortable to use indoors and outdoors.

But it doesn't change color instantly when changing environments, the color change reaction happens more slowly when it's cold, and car windshields   can interfere with glasses changing color.

The   photochromic mirror cannot completely replace the sunglasses. It will not appear dark enough in strong light environments such as beaches and snow,

and   cannot bring enough visual comfort.

Mirrored sunglasses

Specular reflective coatings come in a variety of colors, determined by the thickness and structure of the coating, and the lens is generally brown or gray as   seen by the wearer himself. The reflective coating can reduce the light passing through the lens by 10% to 60%, so it is very suitable for environments with strong   light such as deserts, snow fields, and high altitude areas, and is very popular in extreme sports.

Sunglasses for sports require a specific design, with non-slip nose pads for a more secure fit and wraparound frames to block side reflections.

Sunglasses for babies and toddlers can be chosen in brown or gray color. Gray lenses provide a more natural quality of vision, while brown lenses can help   filter short-wavelength blue light that is harmful to eye health.
