1. Non-polarized sunglasses-single function, not strongly recommended
Generally, sunglasses without polarized lenses are the most general style, and the price is wide and cost-effective, but in terms of filtering ability, it is not optional. The scenery directly in front will be generally dark, although the bright areas are not so bright. It is dazzling, but the dark area is not clear, and the problem of stray light cannot be dealt with. For the natural environment of safe driving with concentration of sight, wearing such sunglasses for a long time will still cause fatigue in the eyes, and there is also There is a certain hidden safety hazard in Xinran, this kind of non-polarizing effect is not recommended to buy.
2. Sunglasses with dark tops and shallow bottoms-can’t protect eyesight in all directions
This kind of sunglasses is also called “gradient color” sunglasses, which is more personalized than monochrome sunglasses. Because wearing sunglasses is to avoid the dazzling sun, the sun is on top, so the upper and lower shades can ensure that they will not be dazzled by the sun. Can recognize the objects underneath, but this kind of sunglasses still has problems for driving. Due to the safe driving of the car, the glare that is harmful to the line of sight does not only come from the sun above, the road surface and the reflection surface of the windshield of the front car. The bright light will also seriously harm the vision of the rear car. In this situation, the gradient shades of the upper and lower shades are not easy to use.
3. Responsive color-changing glasses for myopia-basic waste materials for driving
This kind of color-changing sunglasses is also very common. The basic principle of color-changing is that when ultraviolet light passes through the lens, the lens will produce a chemical change, which makes the lens tone darker. It is also a long-standing technicality, which is relative to the above two. In terms of sunglasses, it is more adaptable and capable of working, but there is a key point that must be paid attention to. The fatal key point is that most of the windshields of family cars on the market at this stage are all capable of filtering ultraviolet light. Yes, so the ultraviolet light that promotes the discoloration of the lens is also unrelentingly filtered by the windshield! Therefore, in the car, color-changing sunglasses will become a waste material. This type of lens is more suitable for outdoor applications, even if it is driving.
4. Wear sunglasses when driving at night?
I really don’t recommend: Friends who often drive at night, what do you feel about the various high beams? “XXX, XXX, XXXXX”, yes, I understand. But in addition to cursing people and applying anti-glare rearview mirrors, there is also a kind of professional “sunglasses” that can be worn at night to help you deal with this annoying problem. This kind of myopia glasses can’t actually be counted as the range of sunglasses. They are special night vision glasses that filter strong light. The lenses are light yellow, which is very easy to identify. At night, it can reduce the chromaticity of high-toughness light sources. It will turn into a mild yellowish color. After the strong light is filtered out, these “backlit” infinite black areas will get better. The price of this kind of night-use “sunglasses” varies from tens to hundreds, but according to the frequency of application, there is actually no need to spend too much. The most important thing is to wear comfortable glasses. If you usually wear glasses for myopia, buy One clip is fine, no more than one hundred yuan.
