Nowadays, many children suffer from myopia, and parents are unwilling to let their children wear glasses early. They will study various methods to protect their children's eyes. Nowadays, popular children's eye protection lights on the market are loved by parents, but are they effective?
There are various types of eye protection lamps on the market, including energy-saving lamps, LED lamps, incandescent lamps, and so on. Some desk lamps with the "eye protection" logo are generally priced between 300 yuan and 1000 yuan. And ordinary desk lamps are generally between 100 yuan and 300 yuan. Both are desk lamps, but the price of eye protection lamps is quite high. However, it is understood that eye protection lamps have not received scientific certification from the national quality supervision department, and many companies have only manufactured a marketing product with a higher positioning.
Meanwhile, some optical experts and ophthalmologists have also expressed that eye protection lamps are still a controversial issue at present. The functions of energy-saving lamps and LED lamps are still under research in the industry, and their benefits for improving or treating vision have not been found yet. So, parents still need to carefully and cautiously evaluate its effectiveness.
The biggest selling point of eye protection lights is "no flicker", but in fact, they are mostly "high-frequency flicker". The high-frequency flashing light appears softer than ordinary light, making reading less tiring and effectively solving visual fatigue. However, in reality, prolonged exposure to such lighting can cause certain damage to a person's eyes and skin.
In addition, eye protection lights that flash at high frequencies also emit strong electromagnetic radiation. Tests have shown that a small eye protection desk lamp emits around 20v/m of radiation, with a maximum of 26.45v/m, while the most commonly used computer has a maximum display radiation of only 2.10v/m. For many teenagers who are still in the stage of physical development, this is undoubtedly a major source of pollution that poses a threat to their health.
