Introduction of Kids Sunglasses
2021-08-24
Children’s sunglasses are designed to protect the eyes from strong light or invisible harmful ultraviolet rays.
The purpose of wearing sunglasses is to protect the eyes from strong light or invisible harmful ultraviolet rays. But if it is not selected properly, it will be counterproductive. So what kind of sunglasses should I choose? When buying sunglasses, you should first choose a firmer one. The color of the lens is preferably gray or smoky. They cause the least color distortion and the best color perception, followed by green or brown. Orange, yellow, red, blue or blue-violet, etc., because their color perception is poor, especially affect the recognition of traffic lights, easy to cause trouble, it is best not to choose.
The best protective lens should be made of high-quality optical glass or plastic. Plastic is more impact-resistant than glass, but the disadvantage is that the surface is easy to wear. When buying a flat lens, you can inspect the lens for scratches, textures, bubbles, spots and other defects against the light. The inspection method is: hold the mirror half of the arm away, look at the doors and windows, etc.
Objects with vertical and horizontal lines move slowly up and down, left and right. If the lines of the object fluctuate, it indicates that distortion has occurred. But lenses used to correct vision cannot be tested in this way, because some distortions are used to correct vision. In addition, check whether the color and depth of the two lenses are the same. Otherwise it will affect the sense of distance and make the eyes feel tired.
The frame should be made of strong plastic or metal, and the ears, nose and temples should be comfortable when worn. Dark-colored frames are better than light-colored frames, because the brightness produced by light-colored frames may damage eyesight.
Improper wearing of sunglasses is prone to eye disease. It is not necessary to wear sunglasses in dark conditions such as cloudy days and indoors. Regardless of the occasion, some people wear sunglasses, regardless of the intensity of the sun, even at dusk, evening, and when watching movies or TV. This will inevitably increase the burden of eye adjustment, cause tension and fatigue of the eye muscles, and reduce vision and vision. Objects are blurred, and symptoms such as dizziness and dizziness may occur in severe cases. Sunglasses are not suitable for babies and children whose visual system development is not perfect. Except for sunglasses with glass lenses, other sunglasses lens materials are not highly wear-resistant. Users should always pay attention to the surface of the sunglasses. When the wear affects the clarity, they should be replaced in time.
Summer is the world of sunglasses, fashion, beauty, and radiation protection. These features make people like wearing sunglasses more. However, relevant experts pointed out that when choosing sunglasses, you must be careful. You can't just focus on the style, but ignore the quality of the sunglasses itself. Do not wear the following four types of unqualified sunglasses:
1. Sunglasses with anti-ultraviolet function. Good sunglasses lenses can block more than 99% of ultraviolet rays, while lenses marked with UV400 can block 100% (99.99%) of ultraviolet rays. Wearing sunglasses with poor UV protection can make the eyes look like in a dark room. At this time, the pupils will become larger, and the residual ultraviolet rays will be injected into the eyes in large quantities, causing damage to the eyes. It is best to go to a specialty store to buy it or buy it at a well-known eyewear network or flagship store. You must not buy enough from the small stalls. Although those sunglasses can also block ultraviolet rays, the lenses are not made in place, which means they are substandard. Do not buy them because they are cheap. Inferior eyes can cause different degrees of damage to the eyes.
2. Sunglasses with unqualified transmittance. After wearing this kind of sunglasses, it will cause traffic signal identification obstacles, which can easily cause traffic accidents. All sunglasses, including professional driving glasses, sports glasses, fishing glasses... (except near-sighted glasses and reading glasses) The easy way to identify is to place the sunglasses in front of your eyes and observe distant objects through the lens, such as window frames or door frames Wait, and then move the glasses up and down back and forth, the target should not swing and wavy deformation.
3. Sunglasses without category identification. Sunglasses are generally divided into three categories, namely, sun-shading mirrors for sun protection, light-colored mirrors for decoration, and special mirrors for preventing snow blindness or water-proof plane radiation. If there is no product category mark, consumers cannot correctly identify the purpose of sunglasses when buying, which will affect the effect of use.

4. Sunglasses whose resistance performance does not meet the requirements. The lens is easily broken when impacted by an external force, and the fragments can cause fatal damage to human eyes. The material of the frame is also very important, generally there are plate, aluminum-magnesium alloy, TR90, and pure titanium. Different needs have different requirements for the sun. There are polarized sports mirrors, polarized driving mirrors, and polarized fishing glasses that are specially used for sports. When buying, you can ask about the professional use of sunglasses. Experts remind consumers that when buying children’s sunglasses, you should go to regular stores to buy well-known brands; you should try them first when buying, and compare whether the color difference changes before and after wearing them are obvious, so that the color of the objects seen after wearing the sunglasses is not distorted Appropriate.
