In the hot summer, Sunglasses have almost become a necessity for fashionable men and women. You know what? In fact, eyes are more afraid of ultraviolet than skin! Ultraviolet radiation can cause eye discomfort in light, and long-term high-intensity ultraviolet radiation may lead to cataract and macular lesions.

But the choice of sunglasses is not simple, not only to consider the beauty and fashion, the choice of lens color is also a university question. Let's take a look at the color selection of sunglasses Gray Lens - the Gray Lens absorbs any chromatogram evenly, so the scenery will only darken, but there will be no obvious color difference. It will show the real natural feeling, absorb infrared ray, 98% ultraviolet light and prevent glare. It can effectively improve the safety index of driving. It belongs to neutral color system. Blue gray lenses - similar to gray lenses, they are both neutral lenses, but have a darker color and higher visible light absorption. 100% perfect absorption of infrared and ultraviolet rays, soft and comfortable colors, no visual fatigue. Tan lenses - filter out a lot of blue light, can improve the visual contrast and clarity, in serious air pollution or foggy conditions wear better. Green Lens - at the same time of absorbing light, maximize the green light reaching the eyes, so it has a cool and comfortable feeling, suitable for people who are easy to fatigue eyes. But the light blocking effect is slightly inferior to that of gray lenses, which is not suitable for driving. Mercury lens - high density mirror coating is used on the surface of the lens. Such lenses absorb and reflect more visible light, suitable for outdoor sports people. Blue lens: you can wear blue lens when you play on the beach. Blue can effectively filter out the light blue reflected by sea water and sky. Blue lenses should be avoided when driving because they can make us not distinguish the color of traffic signals. Yellow lenses - strictly speaking, these lenses are not solar lenses because they hardly reduce visible light, but in foggy and dusk, yellow lenses can improve contrast and provide more accurate vision, so they are also called night vision goggles. Light blue, light pink, etc. -- more decorative than practical lenses. Now the market can also wear degree sunglasses, the color can be selected by themselves, it is really very convenient.

Sunglasses - definition of lens function

According to the transmittance of visible light, the sunglasses can be divided into 1-4 categories from shallow to deep. Class I: light colored Sunglasses (without polarizing function), with 43% ~ 80% of projection, the lightest color, and the least shading and reducing excessive luminous flux. They are generally used for fashion matching glasses, such as model shows, fashion shows, etc. Class II: light colored sunshade mirror (without polarizing function), with transmission ratio of 18% ~ 43%, slightly light color, used in cloudy days or cloudy days. Three categories: sunshade (polarized sunglasses), projection accounted for 8% ~ 18%, most Sunglasses belong to this level, more suitable for seaside, mountaineering and other outdoor activities. Four categories: special purpose sunglasses, transmission ratio of 3% ~ 8%, in skiing, desert, welding and other special environment is more used. Note: according to the requirements, the transmittance of driving glasses should be greater than 8%, so the fourth type sunglasses are not suitable for driving. Polarizing function: the so-called polarizing sunglasses selectively filter the light from a certain direction. By filtering out many polarized light reflected, the intensity of light in the sky is reduced.

Don't choose this kind of sunglasses

In hot summer, people who often go out for activities or work outdoors need sunglasses. Sunglasses can block uncomfortable strong light, while protecting the eyes from UV damage. Economic Daily - China economic network tips, sunglasses purchase to see these elements. First of all, regular brand products should be selected, and the anti ultraviolet function should be clearly marked. According to the international standards, sunglasses are listed as personal protection products. The main function of sunglasses is to block the glare of sunlight. However, the international standard subdivides sunglasses into "fashion glasses" and "general purpose glasses". The standard of "fashion mirror" is relatively low, and it is basically used for decoration. The types of sunglasses can be roughly divided into five types: anti reflective protective lens, color lens, colored lens, polarizing lens and color changing lens. Choose according to your needs and avoid poor quality lenses. Sunglasses can block ultraviolet rays because a special coating film is added to the lenses. However, poor quality sunglasses can not block ultraviolet rays, but also seriously reduce the light transmittance of the lenses. As a result, the pupil will be enlarged, and ultraviolet rays will be injected into the lenses in large quantities, causing damage to the eyes. In addition, poor quality lenses also cause nausea, forgetfulness, insomnia and other visual fatigue symptoms. The shape of the mirror frame can be selected according to the shape of the face. For a round face, the square frame is more spiritual; if it is a long face, the wider sunglasses will make the face look narrower; for the square face with obvious mandibular angle, try to choose the round sunglasses with moderate size.
