UV is an invisible killer,
The eyes are exposed to strong sunlight,
Crystals in the eye can be exposed to too much ultraviolet light
And fiber hardening,
And the damage of ultraviolet to human eyes is cumulative,
It will develop some eye diseases,
Such as cataract, glaucoma, etc.
So what color of lens can protect the eyes most?
1 green lens
Green lens is the representative of pilot series, which can effectively absorb infrared light and 99% ultraviolet light. But green lenses can distort the color of certain scenes. Moreover, its light blocking effect is slightly inferior to that of gray lens, but green is still an excellent protective lens. Green has the function of adjusting eyesight, which is more suitable for students or people with tired eyes.
2 Grey Lenses
The Gray Lens absorbs any chromatogram evenly, so it will darken in case of strong light, but there will be no obvious color difference, showing the true natural feeling, belonging to the neutral color system. It can absorb infrared and 98% ultraviolet. The biggest advantage of gray lens is that the original color of the scene will not be changed by the lens, and the most satisfying thing is that it can effectively reduce the light intensity. Gray can reduce visual fatigue, white-collar workers with more eyes can consider.
3 yellow lens
It can absorb 100% ultraviolet light, and make infrared and 83% visible light penetrate the lens. The biggest feature of the yellow lens is that it absorbs most of the blue light. Because when the sun shines through the atmosphere, it is mainly blue light (which can explain why the sky is blue). After absorbing blue light, the yellow lens can make the natural scenery clearer. Therefore, the yellow lens is often used as a "filter". Yellow is the most sensitive color of visual cells, which can improve the sensitivity of vision. Amblyopia and other poor vision can be preferred.
4 Pink lenses
This is a very common color. It can absorb 95% of the ultraviolet light, and some shorter wavelengths of visible light. In fact, this kind of function is similar to that of ordinary uncolored lens, that is to say, pink lens has no greater protective effect than ordinary lens. But for some people, it's still psychologically helpful because they feel comfortable to wear. There are red and green color blindness or red and green weak person, can choose red lens, it can increase red and green contrast.
5 Brown lenses
This kind of lens absorbs almost the same kind of light as the green lens, but absorbs more blue light than the green lens. Brown lenses cause more color distortion than gray and green lenses, so the satisfaction of ordinary people is also low. But it provides another color choice, and can slightly reduce the blue light halo, making the image clearer.
6 Blue Lens
The beach can wear the sun blue lens, blue can effectively filter out the light blue reflected by the sea water and the sky. Avoid using blue lenses when driving, because it will make us unable to distinguish the color of traffic signals.
In addition to the traditional sunglasses, the so-called "anti radiation, anti blue light, anti fatigue, anti UV" anti blue light glasses have recently become the choice of many people.
The sunlight includes seven bands of "red, orange, yellow, green, blue, indigo and purple". Blue light is one of them, which has relatively high energy.
Blue light is a kind of normal visible light in daily life. The wavelength is about 400 nm, which just falls in the center of the eye, that is, the fovea of the macula. And this part itself is sensitive to strong light, which is mainly composed of optic vertebra cells. If it is stimulated by blue light for a long time, it will suffer some damage.
For people's concerns about the harm of blue light to eyesight, anti blue light glasses have no significant effect on eyesight protection. To protect eyesight, we should pay attention to the health eye, try not to use electronic products for a long time, and do not use the eye for a long time.
