In recent years, many brands of eye protection lamps have appeared on the market, all of which claim that their products can protect the eyes. Many parents have purchased eye protection lamps for their children's health. So, are eye protection lamps really helpful in protecting eyesight? Almost everyone believes that eye protection lamps can protect eyesight, but the question of whether eye protection lamps are useful should be analyzed based on specific circumstances. The fluorescent lamps used in daily life are all powered by alternating current, so as the frequency of the current changes, the light will flicker continuously. Due to the rapid frequency of change, the flickering of the fluorescent light is invisible to the human eye. Reading and writing under this kind of flickering light for a long time will be very bad for eyesight, especially for teenagers who are in the development and growth period. The eye protection lamp has undergone special technical processing to reduce the flicker of light or even eliminate it completely. At the same time, the light of the eye protection lamp simulates the color of daylight, which is very helpful in protecting eyesight. However, the prices of eye protection lamps from many brands on the market vary greatly, with the cheapest being only a few dozen yuan and the most expensive being several hundred yuan, so parents must go to regular stores to purchase qualified quality products. Eye protection lamps have a certain effect in protecting eyesight, but they must be used correctly, otherwise it will be counterproductive. Some friends mistakenly believe that the brighter the light is, the better for reading and writing, so they like to use overly bright eye protection lamps. Too much light or too little light can damage your vision. Therefore, try to buy an eye protection lamp with a power not exceeding 10 watts, as the light is softer. In addition, we must avoid another misunderstanding when using eye protection lamps. Some people think that the whiter the light, or even a little bluish, the best. This view is wrong. Such light will cause people to have color bias, and the impact will be more obvious for young friends. If you use your eyes under such light for a long time, it will cause color blindness. In this case, the eye protection lamp will become a helper in damaging your eyesight. |
