What color is good for sunglasses? The depth of the lens color only affects the absorption of visible light and has nothing to do with UV resistance. UV resistance is only related to the lens material.
There are several colors of sunglasses:
Gray: There will be no chromatic aberration when looking at the scene and the characters, it will only darken, showing a real and natural feeling, belonging to the neutral color system.
Brown: Filters out a lot of blue light, improves visual contrast and clarity, and is suitable for wearing in heavily polluted or foggy conditions.
Green: It is a neutral color like gray because it can increase the green light reaching the eyes, so it is cool and comfortable, suitable for people who are prone to eye fatigue.
Blue Gray: Like gray, it belongs to a neutral color system, with a darker color and a higher visible light absorption rate.
Mercury lens: The lens surface is coated with high density. Can absorb and reflect more visible light, suitable for outdoor sportspeople.
Yellow: Strictly speaking, this lens is not a sunglasses, because it can hardly filter light, but it can improve the contrast and provide more accurate vision, so it is also called "night vision goggles", of course, it can also be used for decoration.
Light colors such as light blue and light pink: decorative rather than practical.
If the purchase of sunglasses is mainly based on practicality, polarizers from ANRRI EYEWEAR are recommended; 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. The result is that the pupils are enlarged, which makes the lens of the eye absorb more ultraviolet rays, so be sure to choose a reputable store to buy.
So what should you pay attention to when buying sunglasses?
First, observe whether the lens has scratches, impurities, bubbles, stripes, 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. Sunglasses that are UVA and UVB marked are the only way to ensure that certain UV rays are blocked.
Second, when purchasing sunglasses, try wearing them for dizziness and headaches. There are also some myopic sunglasses on the market that are marked with degrees, but because indicators such as interpupillary distance vary from person to person, consumers are best not to choose such sunglasses without professional guidance.
Third, place the two corners of the sunglasses against the fluorescent lamp with your hands, so that the reflective strips of the mirror roll smoothly. If you notice wavy and distorted shadows reflected by the lenses, it is a sign that the lenses are not flat, and such mirrors can damage your vision.
Fourth, the lenses should be flat and the transparency should be high. The sun lenses are made of glass and resin, and the best sun lenses should be polarized lenses. It is made of synthetic resin that is as light and precise as contact lenses. Polarized lenses effectively filter out reflected light and harmful UV rays, so they are the most popular sunglasses.
Fifth, the color of sunglasses should not only be matched according to their skin color, face shape, and clothing but also should be selected according to the place of entry and exit. Generally speaking, the filter effect of black, brown, and gray is good; gray lenses can absorb any color spectrum evenly, and the scene seen after wearing the glasses will only become darker without obvious chromatic aberration; brown lenses can filter out a lot of Blue light, which improves visual contrast and clarity, especially when worn in heavily polluted or foggy conditions.
Sixth, what shades of sunglasses are suitable for us? A simple self-assessment method is to put on sunglasses in front of the mirror, to the limit that you can vaguely see your pupils. If the color is too light, the filtering effect is too small; if the color is too dark, it will affect the vision and weaken the color perception. The popular colorful and light-colored sunglasses this year should not be used in seaside water activities, in the snow with strong reflection, and the sun with very strong sunlight, but should be worn with sports sunglasses. Most of them use bright saturated colors, which can absorb or Reflects more visible light.
Seventh, in addition to reducing the stimulation of strong light, wearing sunglasses can protect the eyes from UV rays and prevent damage to the retina. So be sure to choose lenses with UV protection logos. Usually, the UV index of sunglasses is between 96%-98%.
Eighth, regular optical shops will have instruments to detect the ability of sunglasses to resist UV rays. With this test, you can know if the glasses in your hand are helpful for your eye health. What color sunglasses are best? In the choice of lens color, from the perspective of the effect of blocking light, gray and brown sunglasses should be selected as much as possible. Compared with other colors, lenses of this color can more effectively maintain the color of the object itself and can filter harmful ultraviolet rays. substance. In addition, some children wear sunglasses indoors and outdoors to "play cool". This is not advisable. When the sun is hot outdoors, you can wear sunglasses to protect your eyes, but you should take off your sunglasses indoors, because the indoor light is dark, and wearing dark sunglasses will cause long-term eye fatigue, resulting in eye muscle tension and blurred vision.
