Why do many people wear brown glasses? It is said that it is best to wear a pair of brown glasses when playing electronic products such as mobile phones and tablets before going to bed, because this will help improve the quality of sleep and improve insomnia. Today, let's learn about the benefits of wearing brown glasses!

Why do many people wear brown glasses?

People wear sunglasses for three purposes: to prevent ultraviolet rays from burning their eyes, cataract patients rely on glasses to reduce the stimulation of visible strong light to their eyes, and to reduce the damage of infrared rays to the fundus through the lens of human eyes. However, colored glasses are not always able to block ultraviolet rays. Only when lenses are coated with anti-ultraviolet films can they be used as sunglasses.

Color separation introduction

(1) tan: tan sunglasses are recognized as the best lens color. It can absorb almost 100% ultraviolet and infrared rays, and the soft color tone makes the eyes very comfortable and less tired.

(2) Gray system: It can completely absorb infrared rays and most ultraviolet rays without changing the original color of the scene. Mild and natural colors are popular lens choices.

(3) Green system: Like gray glasses, it can absorb all infrared rays and 99% ultraviolet rays, and the blue and red rays in the light can also be blocked, but sometimes it will change the color of the scene after passing through green lenses. However, because green brings people a cool and comfortable feeling and good eye protection effect, it is also the first choice for many friends.

(4) Yellow series: Yellow series lenses can absorb 100% of ultraviolet rays and most of blue light, and the scenery will be clearer after absorbing blue light, so it is more common to wear yellow lenses as filters when hunting and shooting.

(5) Red: The red sunglasses lenses have good blocking performance for some light with short wavelength, while the other protective effects are lower than the other three colors.

(6) In addition, it is particularly emphasized that you should try not to choose sunglasses with pure blue lenses. Pure blue lenses will pick out harmful blue light and enter the eyeball, which is not conducive to eye health. Through this comparison, we should be able to see what color sunglasses are and make the right choice according to our own needs and preferences. Colored glasses protect eyes in the sun, provided that they can prevent ultraviolet rays. For colored glasses that do not protect against ultraviolet rays, it is harmful in the sun, but wearing colored glasses indoors is definitely harmful to vision, so wearing brown glasses is very popular.
