What color is good for sunglasses? Let’s talk about the lenses of sunglasses. The sunglasses are divided into four types according to the depth. The 15%, 34%, 50%, 70%, and 15% depths are the shallowest. They are suitable for indoor and outdoor wear, especially for the eyes. People with degrees can avoid the trouble of taking off and wearing. 34% depth, suitable for general sun exposure. 50% of the sunglasses can be worn in the hot sun and on the beach. 70% of sunglasses are special-purpose and are generally used in engineering such as electric welding.
The depth of the lens color only affects the absorption of visible light, independent of the ability to resist ultraviolet light. The UV resistance is only related to the lens material.
Then introduce the color of the lens.
Gray: For any chromatographic absorption, the scene will not appear chromatic aberration, only darken, showing a truly natural feeling, belonging to the neutral color system.
Brown: It can filter out a lot of blue light, which can improve visual contrast and sharpness. It can be worn well in case of serious air pollution (such as sandstorm) or fog.
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 whose eyes are easy to fatigue.
Blue ash: It is a neutral color like gray. It has a darker color and a 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, these lenses are not sunglasses, because they hardly reduce visible light, but can improve the contrast and provide more accurate video, so it is also called “night vision goggles”, of course, can also be used for decoration.
Light blue, light pink and other light colors: decorative is more than practical.
If you buy sunglasses for practical use, recommend the French CABE polarizer; if you want to consider the decorative effect of sunglasses, it is better to use colorful lenses.
Inferior sunglasses are unclear and can’t resist ultraviolet rays. As a result, the pupils are enlarged, so that the lens of the eyes absorbs more ultraviolet rays, so it is necessary to choose a reputable store to buy. So what should I pay attention to when buying sunglasses?
First, first observe whether the lens has scratches, impurities, bubbles, streaks, and check the outer packaging of the sunglasses. Regular sunglasses should be marked with the name, color, diameter, quality level, manufacturer name and trademark, and the mirror or tag is marked. UVA, UVB, and CE marked
Sunglasses ensure that certain UV rays are blocked.
Second, you should wear a pair of sunglasses to try to have a feeling of dizziness and headache. There are also some myopia sunglasses on the market that are sold, but because the distance and other indicators vary from person to person, consumers should not choose this kind of sunglasses without the guidance of professionals.
Third, hold the two corners of the sunglasses against the fluorescent lamp, and let the reflective strip of the mirror gently roll. If the specular reflection of the fluorescent lamp appears wavy and twisted, it proves that the lens is not flat, and such a mirror will damage the vision.
Fourth, the lens should be flat and the transparency should be high. The sunglasses should be 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 made up of seven layers of sheets. The outermost two layers are super-hard wear-resistant layers; the second and sixth layers are shatterproof layers; the third and fifth layers are UV rays. The filter layer, the middle layer is the polarizing filter layer. Polarized lenses are the most popular sunglasses because they can effectively filter out reflected light and harmful ultraviolet rays, and have the functions of shatterproof and anti-war.
Fifth, the color of sunglasses should be selected according to the skin color, face shape, and wear. In general, the black, brown, and gray filters have good filtering effects; the gray lenses absorb evenly in any chromatogram, and the scenes seen after wearing the mirror will only darken without a significant color difference; the brown lenses can filter out a large amount. Blu-ray can improve visual contrast and sharpness, especially when exposed to heavy air or fog.
Sixth, how is the color shade of sunglasses suitable for us? The simple self-test method is to wear sunglasses on the mirror, to the limit of seeing your own coix. 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.
