In fact, when we use computers every day, we should not forget to take care of our skin. Many people's eyes are highly radioactive, so everyone needs to wear anti-radiation glasses. When choosing anti-radiation glasses, you must not choose cheap ones just for the sake of cheapness, because these are eyes after all. The glasses that need to be worn must be certified by a regular medical institution and must have the same effect. Identification method 1. Because the surface of the radiation-proof lens is coated with a radiation-proof film. These films are ordinary anti-radiation films, and according to national testing, the anti-radiation effect can reach about 50%. The latest technology uses 18 layers of synthetic lenses, and according to testing by the National Defense Committee, the protection rate can reach more than 99%. 2. Wear it and look at the computer to see the different feelings. For example: when you look at the computer without wearing any anti-radiation glasses, you will feel that the monitor is particularly dazzling and slightly jumps. If you wear anti-radiation glasses, you will feel clear and natural vision. A famous ophthalmologist said that anti-radiation glasses are made by adding compound media to the manufacturing materials during the lens processing process, and then coating the lenses with an anti-radiation film. They can play a certain filtering role to a certain extent. This is because the radiation from computers and other devices comes from electromagnetic waves, which have a certain wavelength and amplitude. Compound media and anti-radiation films use this principle to make the electromagnetic waves of different wavelengths generated on the front and back surfaces of the lens interfere with each other, thereby offsetting part of the radiation. Ophthalmologists also remind everyone not to wear colored lenses for a long time when facing computers, televisions and other monitors, because colored lenses can easily cause the sensitivity of photoreceptor cells in the eye to decrease or even disappear, which may lead to color weakness and color blindness. Wearing Guide 1. Strict wearing regulations Wear and remove contact lenses in a standardized manner according to the instructions of the wearer and the instructions to prevent the lenses from being damaged by nails, clips or sharp objects. 2. Special inspection before wearing According to examination by professional ophthalmologists, people with trachoma, keratitis, conjunctivitis, hypertension, diabetes, endocrine disorders and other diseases, as well as minors, should not wear contact lenses. 3. Usually, the first-time wearer should go to the wearing center for examination after one week. Regular wearers should have their lenses checked every three to six months. If any problems are found after use, they should go to a wearing center for a check-up at any time to ensure eye hygiene. 4. Prevent chemical damage Contact lens wearers who use cosmetics must follow the principle of putting on lenses before applying makeup, and taking off lenses before removing makeup, to prevent shampooing, skin care and beauty chemicals from damaging the lenses. 5.Store safely and hygienically Take off the lenses and put them into a special lens box and immerse them in care solution. The lens box must be disinfected and hygienic, and prevent the lens cover from crushing the lenses. |
