You know that your eyes need sun protection, too.

Now we all have a strong sense of sunscreen. In summer, it is all-round sunscreen. Even many people take good sunscreen measures all year round. But there are not many people who protect their eyes from the sun.

The ultraviolet and infrared rays in the sun will damage the cornea, lens and even the fundus of the eye, increasing the risk of cataracts. When the UV index is more than 2, we should pay attention to sunscreen. At this time, we need a pair of reliable sunglasses to protect our eyes.

Different color absorption capacity is different

At present, there are more and more sunglasses on the market, which can be roughly divided into five types: tea, gray, yellow, green and red. The sun protection effect of different color systems is also very different.

Tea color series

Tan Sunglasses products are recognized as the best lens color, it can absorb almost 100% ultraviolet and infrared rays; and soft color makes the vision comfortable, so that the eyes are not easy to fatigue.

Grey series

It can completely absorb infrared rays, and most of the ultraviolet rays, and will not change the original color of the scenery. Mild natural color is a popular choice for lenses.

Yellow series

The yellow lens can absorb almost 100% ultraviolet and most of the blue light. After absorbing the blue light, the scene will be clearer.

Green series

It can absorb all infrared rays and 99% ultraviolet rays. The blue and red in the light can also be blocked, but sometimes the color of the scenery will be changed after passing through the green lens.

Red series

The Red Sunglasses have a good barrier to some short wavelength light, while the other protective effects are lower than those of other color systems.

There is a misunderstanding among the public that the darker the lens color, the better to avoid the sun stimulation. In fact, the darker the lens color is, the larger the pupil is. If the sunglasses do not have qualified filtering function, the damage to the eyes will be greater. The most important thing is the light transmittance.

The national quality standard for sunglasses is that they can penetrate more than 95% of the ultraviolet rays, the transmittance should be about 5% - 30%, the color of the lenses on both sides should be uniform and the difference should not be more than 5%, they should not deform or change color when looking at things, and they should wear comfortably and brightly.

Glasses, it's better to put them in the protective cover when they are not in use, and prepare a glasses cloth inside to prevent the lens from being scratched; in addition, don't put the sunglasses on the center console casually, especially in the hot summer, the sunglasses will really deform after being exposed to high temperature, especially the plastic frames and resin lenses; so we should pay attention to your glasses.
