(Summary description) As we all know, prolonged exposure to ultraviolet radiation will kill a large number of human cells. So, how many people pay attention to the invisible ultraviolet rays contained in ordinary energy-saving lamps and fluorescent lamps, and how many people know how harmful it is to the human body? American biochemist Anderson found that people who lived or worked under fluorescent lights for a long time received 50% more ultraviolet radiation than those who did not often receive fluorescent lights, and their skin cancer rates were also higher than normal. People are much taller.

However, tests have shown that most fluorescent lamps have varying degrees of UV radiation, and some UV radiation even reaches the level of disinfection and sterilization. The Shanghai Lighting Society conducted a survey on topics such as "the relationship between lighting and adolescents' vision health". Among them, Professor Xu Xueji of the Institute of Electric Light Sources of Fudan University found in the process of testing a variety of energy-saving fluorescent lamps on the market that one of them actually emits ultraviolet rays of 254 nanometers. Xu Xueji said that this result is very surprising, because fluorescent lamps use ultraviolet rays to excite phosphors to emit light. All fluorescent lamps (including energy-saving fluorescent lamps) will have ultraviolet rays, but the ultraviolet rays in those lamps are so strong that they can be directly used for disinfection and sterilization. If it is used for short-range lighting, it is very likely that the eyes will be harmed unknowingly.

When the distance from the fluorescent lamp is 1 to 2 meters, the ultraviolet rays will have a certain degree of damage to the human eye, and within 0.6 meters (generally the height of the lamp does not exceed this distance), the damage will be aggravated. In addition, due to the promotion of energy-saving fluorescent lamps, the number of households using fluorescent lamp table lamps in large and medium-sized cities has increased from about 20% five years ago to about 40% now, which makes the potential harm of ultraviolet fluorescent lamps continue to increase.

An important reason why there are more cataract patients in plateau areas is that the ultraviolet rays in the sun are strong.

Relevant experts suggested that, first of all, you should look for products that have passed the sampling inspection by authoritative institutions such as the National Electric Light Source Product Quality Supervision and Inspection Center, and secondly, don't be greedy for cheap and buy inferior products that are too cheap on similar stalls. However, experts pointed out that ultraviolet rays are invisible light, and consumers cannot see whether there is or how much. The root of the problem is that, so far, there are no domestic regulations to limit the ultraviolet radiation of fluorescent lamps. Therefore, in order to protect the health of citizens, especially to effectively protect the eyesight of young people, experts call on relevant departments to introduce a market access system to prevent "ultraviolet lamps" from harming the people.
