What color are sunglasses good for eyes? What color are the sunglasses?

In summer, the sun is strong, especially outdoors. In many cases, strong sunlight can make people unable to open their eyes, so many people use sunglasses to keep out the sun. There are all kinds of sunglasses on the market now, and many people are very upset when they buy them. I don't know which glasses have good eye protection effect, and what color sunglasses are good for eyes?

1, sunglasses color classification

On the whole, the best lens colors of sunglasses are dark brown, gray, green and other light-colored lenses, which are the best in both visual effect and protective effect.

2. The first choice for driving is dark brown lenses.

Dark brown lenses can filter a lot of blue light and improve visual contrast and clarity. Generally, it can block the reflected light from a smooth and bright surface, and the wearer can still see the subtle parts clearly. Dark brown lenses can completely absorb purple and cyan in light, and almost absorb 65,438+0,000% ultraviolet and infrared rays. Soft tone makes eyes not tired, which is an ideal choice for drivers.

3. Choose the gray system for outdoor play.

Gray lens sunglasses filter almost the same amount of sunlight, which can filter infrared rays and 98% ultraviolet rays. Wearing sunglasses with gray lenses will not change the original color of the scene because of the lenses, and it can also block the strong light to the maximum extent.

4. Green prevents ultraviolet absorption.

Nowadays, the popular green sunglasses have the same effect as gray sunglasses, which can not only filter infrared rays, but also filter 99% ultraviolet rays. But green lenses can change the color of some scenery. Fortunately, green is a natural sedative that can make you feel quiet and comfortable.

5. Red is only for decoration.

In fact, sunglasses with red lenses do not have a good eye protection effect. Because the red light blocking effect is poor, this color of sunglasses is not recommended, but this color of sunglasses will bring a certain sense of fashion to the whole. You can choose to wear it when the sun is not strong.

6. Outdoor talents choose polarizers

A polarizer only allows light in a certain polarization direction in natural light to pass through the lens. Polarizer filters out the glare in the same direction when the sun shines on sleep, land or snow. Adding a vertical special layer to the lens is called a polarizer. Due to the filtering effect of polarizer, the light of the object seen by the eyes will darken after wearing. Therefore, these glasses are more suitable for sea sports, skiing or fishing.

7. Matters needing attention in purchasing sunglasses

1. With anti-ultraviolet mark.

UV protection is the primary function of sunglasses. Some sunglasses have "100% UV protection", "UV400" and "UV protection" on their lenses or packaging. If you wear inferior sunglasses that can't block ultraviolet rays, more ultraviolet rays will enter your eyes than when you don't wear sunglasses, which will easily lead to eye damage. After a long time, it will lead to cataract, eye pain, corneal edema, corneal epithelial shedding and other symptoms. Regular optical shops generally have instruments to detect the anti-ultraviolet ability of sunglasses, which can detect whether your choice is correct. The glasses of street stalls and vendors often do not meet the standards, so it is best not to buy them.

2. Choose gray, brown and green lenses.

The selection of lens color should be based on the principle of undistorted surrounding environment color, clear object edge and effective recognition of different color signal lights. The colors of lenses are gray, brown and green, because these colors of lenses absorb infrared and ultraviolet rays better.

3. Medium depth lens

Generally speaking, the darker the color of the lens, the stronger the shading effect, but it does not mean that the anti-ultraviolet ability is stronger. The anti-ultraviolet function of sunglasses is also related to the material and technology of lenses. Generally, lenses with medium depth are better. Of course, if you need a strong shading effect, you should choose a darker lens. But cyclists or drivers can't choose too dark lenses, otherwise it will be difficult to identify the color of traffic lights.

4. The occasion determines the angle of choice

When going out for activities, you should choose different sunglasses for different occasions. For example, some sports sunglasses have special frames to protect their eyes according to different needs, which can be worn comfortably and firmly, such as water skiing, skiing, mountain climbing, golf and tennis. For people who like golf and tennis, amber lenses can effectively increase the contrast, absorb blue light and contribute to the visual comfort in sports.

When swimming outdoors, it's best to wear goggles treated with ultraviolet protection. Drivers and fishing enthusiasts had better choose polarized lenses, because polarized lenses can eliminate glare from all directions and make objects look clearer.

5. Let sunglasses add points to beauty.

Generally speaking, different people will choose sunglasses according to different preferences and different uses, but the most fundamental thing is to start from the basic principle of protecting the wearer's eyes from injury. The basic function of sunglasses should be to reduce the strong light stimulation, keep the vision clear and undistorted, prevent ultraviolet rays, identify colors undistorted and accurately distinguish traffic signals.

In addition, when buying sunglasses, you have to consider whether they match your eye size, face shape, eyebrows and nose. If your eyes are big, you can choose glasses with large frames, and if your eyes are small, you can choose glasses with small frames. A round face is suitable for wearing a thick frame, a thin face is suitable for a round frame, and a flat round face should choose a slightly narrow box up and down.
