What color is good for sunglasses lens

    What color sunglasses are good? Let’s talk about the lenses of sunglasses first. Sunglasses are divided into four types according to the depth, followed by 15%, 34%, 50%, 70%, and 15%. The depth is the shallowest, suitable for indoor and outdoor wear, especially for those with eyes. People with degrees can avoid the trouble of taking it off and putting it on. 34% depth, suitable for use under general sun exposure. 50% of the sun glasses can be worn in the hot sun and by the sea. 70% of the sunglasses are for special purposes, and are generally used in engineering professions such as electric welding.

     The depth of the lens color only affects the absorption of visible light, and has nothing to do with the ability to resist ultraviolet rays. UV resistance is only related to the lens material.

     Then tell me about the color of the lens.

     Gray: It absorbs evenly for any color spectrum, so there will be no color difference when viewing the scene, it will only become darker, showing a real and natural feeling, and it belongs to the neutral color system.

     Brown: It can filter out a lot of blue light, which can improve visual contrast and clarity, and it has a good wearing effect in severe air pollution (such as sandstorms) or foggy conditions.

     Green: Like gray, it belongs to the neutral color system, because it can increase the green light reaching the eyes, so it is cool and comfortable, suitable for people whose eyes are prone to fatigue.

     Blue gray: Like gray, it belongs to the neutral color system, with darker color and higher visible light absorption rate.

Mercury lens: The surface of the lens is coated with high density. Can absorb and reflect more visible light, suitable for outdoor sports people.

     Yellow: Strictly speaking, this type of lens does not belong to sunglasses, because it hardly reduces visible light, but can improve contrast and provide more accurate video, so it is also called "night vision goggles". Of course, it can also be used for decoration.

     Light blue, light pink and other light colors: decorative rather than practical.

     If you buy sunglasses mainly for practicality, we recommend polarizers from CEBE in France; if you want to consider the decorative effect of sunglasses, it is better to choose colorful lenses.

     Inferior sunglasses can't see clearly and can't resist ultraviolet rays. As a result, the pupil dilates and the lens of the eye absorbs more ultraviolet rays, so be sure to choose a reputable store to buy. So what should you pay attention to when buying sunglasses?

     First, first observe whether there are scratches, impurities, bubbles, or streaks on the lens, and check the outer packaging of the sunglasses. Regular sunglasses should be marked with the product name, color, diameter, quality level, manufacturer’s name, and trademark, and the mirror or tag should be marked UVA, UVB and CE marked

Sunglasses can ensure a certain amount of UV protection.

     Second, when purchasing sunglasses, wear them and try to see if you feel dizzy or have a headache. There are also some myopic sunglasses marked with degrees on the market, but because the interpupillary distance and other indicators vary from person to person, consumers are best not to choose such sunglasses with degrees without the guidance of professionals.

     Third, hold the two corners of the sunglasses against the fluorescent lamp, and let the reflective strip on the mirror surface roll smoothly. If you find that the fluorescent lamp shadow reflected by the mirror surface appears wavy or distorted, it proves that the lens is not flat, and such a mirror surface will damage eyesight.

     Fourth, the lenses should be flat and have high clarity. Sunglasses are made of glass and resin, and the best sunglasses should be polarized lenses. It is made of the same lightweight and precise synthetic resin as contact lenses. It is composed of seven layers of flakes. The outermost two layers are superhard wear-resistant layers; the second and sixth layers are anti-shatter reinforcement layers; filter layer, the middle layer is a polarizing filter layer. Polarized lenses can effectively filter reflected light and harmful ultraviolet rays, and have functions such as shatterproof and wear-resistant. They are the most popular sunglasses.

     Fifth, the color of sunglasses should not only be matched according to your skin color, face shape, and clothing, but also according to the places you enter and exit. Generally speaking, black, brown, and gray have good light filtering effects; gray lenses can absorb any color spectrum in a balanced manner, and the scene seen after wearing the glasses will only become darker without obvious chromatic aberration; brown lenses can filter out a lot Blue light can improve visual contrast and clarity, and is especially effective when worn in severe air pollution or foggy conditions.

     Sixth, what color shades of sunglasses are suitable for us? A simple self-test method is to wear sunglasses in front of the mirror, so that you can vaguely see your own pupils as the limit. If the color is too light, the filtering effect will be too small; if the color is too dark, it will affect vision and weaken the sense of color. The colorful light-colored sunglasses that are popular this year should not be used in seaside water activities, in the snow with strong reflections, and under the sun with strong sunlight. Instead, you should wear sports sunglasses. Most of them use bright saturated colors, which can absorb or Reflect more visible light.

     Seventh, besides reducing strong light stimulation and making eyes comfortable, the main purpose of wearing sunglasses is to prevent ultraviolet rays from causing damage to the eyes. However, the color of the lenses and whether they are UV-resistant are two different things. Even if the lenses are dark in color, they may not be able to effectively prevent UV rays. So be sure to choose lenses marked with anti-UV function. Usually the UV index of sunglasses is between 96% and 98%.

     Eighth, regular optical shops will have instruments to test the ability of sunglasses to resist ultraviolet rays. Through this test, you can know whether the glasses in your hand are helpful to your eye health. What color sunglasses are good? In the choice of lens color, from the perspective of the effect of blocking light, you should try to choose gray and brown sunglasses. Compared with other colors, lenses of this color can effectively maintain the color of the object itself and can filter harmful ultraviolet rays. substance. In addition, some children wear sunglasses indoors and outdoors in order to "play cool". This is not advisable. You can wear sunglasses for eye protection outdoors, but you should take off the sunglasses when you go indoors. Because the indoor light is dark, wearing dark sunglasses will cause long-term eye fatigue, eye muscle tension, and blurred vision.

     In addition, when buying sunglasses, it is necessary to distinguish between protective sunglasses and decorative sunglasses. Decorative sunglasses do not have UV protection and cannot resist the sun's damage to the eyes.
