No strobe, no radiation, no UV, eyesight, delaying eye strain, and preventing myopia.... These are the signs that attract countless “everything for children†parents who spend more than regular desk lamps. Several times the price to buy eye protection. However, the so-called eye lamp is really effective? It really can play a role in protecting eyesight and delaying fatigue? The reporter conducted a market survey on this issue found that high eye protection The magical effect of the lamp may just be a conceptual hype of the business.
Market Research Says Eye Care Businesses Can't Tell Reasons Recently, Jinghua Household Reporter conducted a survey on a large lighting market selling eye protection lamps as a consumer. For what is eye protection lamp, eye protection lamp why eye protection? The statements of various businesses vary, and some are even inconsistent.
In a shop in the large-scale lighting market in the Southwestern Metropolis of Bandung, the reporter expressed his intention to purchase eye protection lamps. The sales staff introduced a row of “table lamps†with the same appearance as ordinary table lamps. Sales staff introduced: "This kind of lamp has electronic ballast, not flash, ordinary lamp is a light bulb, nothing else, and this light bulb is also special, so it can play a role in eye protection." She also let the reporter straight Contrast the lamp of the ordinary table lamp and the eye lamp, she described that the lamp of the ordinary table lamp was dazzling and the lamp of the eye was not felt. Therefore, the eyes were not tired and the child's eyes were not easy to be nearsighted. However, after the reporter saw it, the difference was not obvious, so he asked if the lamp should be replaced after the lamp was broken. The salesman said that changing an ordinary lamp would do. When reporters asked her not to say that the eye lamp used was a special lamp? How is the normal lamp now? The salesman avoided answering, saying that this eye protection was good, and she sold three in the morning.
The Jinghua Household Reporter then went into a brand store and saw some lamps with “no strobeâ€, “no radiationâ€, and “no glare†printed on the desk lamp. The salesman introduced this to the eye protection lamp. Since there are electronic ballasts inside, the lights do not flash and the eyes are not tired. In another shop, the clerk introduced the eyes of the lamp because it uses three-color lamps. The clerk also removed the lamp to the reporter. The reporter found that the word "tricolor" was indeed attached to it, but it did not show any difference with the ordinary lamp. In another brand franchise store, four or five lamps are also emblazoned with "No strobe", "No glare", "No radiation", "No noise" and other publicity cards. When a reporter asks how to protect his eyes, Shopping guide only shows that the manual has relevant functions and did not make any introduction. In the circle of the city, the reporter did not get the exact explanation of the concept of “no flicker†and “no glare†advocated by the eye-protection lamp. How to protect the eye is different, and people are puzzled. .
Although the business is generally unclear, the price of an eye protection lamp that is eye-protecting is not at all vague. Reporters visited and found that eye protection lamp prices are generally more than 100 yuan, most of the price is between 200-400 yuan, and some brands of eye protection lamp prices as high as 500 yuan. The reporter had conducted comparisons in the store. In the same business, the price of an ordinary table lamp was only 70 yuan. The appearance of the eye lamp with the electronic ballast was similar to that of an electronic ballast but it was 260 yuan.
Paying attention to health consumers, after paying a scant price, reporters found that businessmen generally mention professional terms such as strobe, glare, color temperature, electromagnetic radiation, and ultraviolet radiation in the promotion of eye protection lamps. Many shopping guides are very rough when introduced, and some of them are It does not understand at all, and it is difficult for consumers to have a firm understanding of product functionality. Even if someone is introduced in more detail, people who lack professional knowledge are not always easy to understand.
Reporters randomly interviewed several consumers who are eye-safety lights for children in the City of Lights. They said that they are not very clear about what they are eye-protection lights. They don’t understand how they listen to shopping guides, but they always have products for children. Benefits will do. A woman who is currently opting for eye protection is quite representative: "Protecting the child's eyes is very important. The introduction of eye protection lamps is so versatile and the price is so high. Compared with ordinary lamps, there are more children than children. Benefits, so it's worth spending more money."
The reporter’s notes end this show, and the enthusiasm of the merchants and the enthusiasm of consumers are particularly evident on eye protection. Through the children's health, businesses have played a dazzling concept of product shows, but the efficacy of eye protection in the end, few people in the company made it clear. The reporter interviewed a certain brand of lighting companies, and their eye protection principles were rejected by experts one by one. When a reporter contacted the China Illuminating Society to conduct an interview on the actual efficacy of eye protection, the staff member responded to the reporter and said: “Companies can only explain the function of the lights, but can these functions be able to speak clearly? You still look for an ophthalmologist!†According to experts, eye protection is actually no different from a desk lamp, even if it is indeed higher than the national standard that a table lamp meets in some respects, but because some indicators cannot be detected, people have to The effect is doubtful. Instead of focusing on creating concepts, it would be better to be realistic and make some real products. Otherwise, it is not only the consumers but also the entire industry who are eye-safe.
The concept of expert opinion Fluctuation The concept of “No flickerâ€, “No glareâ€, “No radiationâ€, “No UV lightâ€, and “No noise†were played by the outsiders. The reporter interviewed related experts in this field. After analyzing each concept one by one, the experts pointed out that although some indicators have certain benefits for delaying visual fatigue, they are not very different from the general table lamps that meet the national standards and are used by parents. Psychologically to hype, "at best, is a normal table lamp!"
No flicker is not scientific Some businesses introduce the strobe light produced by ordinary table lamp light source will cause eye fatigue, leading to myopia. Yang Zheng, an expert on electric light sources, introduced that the word strobe was created by the company itself, and electric light sources do not have this terminology. It actually refers to a kind of light output fluctuation generated by the luminous body under the condition of AC power supply. This fluctuation is visible under the instrument, but it is hard to be perceived by human eyes. It is unscientific for traders to advertise their use of electronic ballasts so that the lamp does not have such a "strobe". He said that the use of electronic ballasts to increase the operating frequency of the lamp can only speed up this fluctuation so that the human eye becomes even more imperceptible. So you can only say "high frequency flash" instead of "no flash". Yang Zheng also said that currently all qualified lamps use electronic ballasts. This is not unique to eye protection. However, the lights that do not really have “strobbling†need DC power supply, but according to Yang Zheng, this kind of lamp has not yet been produced in China due to technical reasons.
Lin Yandan, an associate professor at the Institute of Electric Light Sources at Fudan University, introduced that studies abroad have shown that the higher the “strobe†is, it does have a certain benefit for delaying visual fatigue. However, there is currently no measurement standard to measure it.
Is it possible that there is no possibility of “radiation-free†that businesses claim to have no radiation? Lin Yandan pointed out that this argument is unscientific. Excessive electromagnetic radiation generated by electric light sources is indeed harmful to the body, so the national standards strictly regulate the radiation value of electric light sources. However, as long as it is in line with national standards, products should be safe to the human body. The so-called "no radiation" can only be the product's radiation is lower or lower than the national standard, and no radiation can not be achieved at all. Yang Zheng also introduced that on the current test of the lamp, most of the desk lamp's electromagnetic radiation is lower than the national standard, which is not unique to the eye lamp.
No ultraviolet rays Do not worry too much if the electric light source produces excessive ultraviolet rays to cause harm to the human body really, Lin Yandan introduces, the country also has strict regulations in this respect, so it is safe to use the lamps and lanterns that accord with the national standard. Yang Zheng also said that the UV light generated by the qualified lamps is very small, and consumers need not worry too much.
Glare-free glare is a good solution Yang Zheng pointed out that the simple understanding of glare is that the eyes can see the light at the same time when they are reading normally, which will cause discomfort. The country has specific requirements in this regard in the “performance requirements for reading and writing desk lampsâ€. Even if the table lamp used by consumers produces glare, you can solve it by using newspapers, etc. to block the lights. This is not enough to be an eye protection. Lights advertised selling points.
No noise is difficult to achieve national standards require table lamps noise should not be greater than 35 decibels, Yang Zheng pointed out that as long as the standards should not interfere with people, and businesses say no noise can only make the noise as small as possible It is difficult to achieve the "nothing" standard.
Color temperature according to individual needs and set up a lot of businesses to introduce their own color temperature lamp is very conducive to protecting the eyes, and Yang Zheng introduced, in fact, color temperature is only concerned with the degree of reduction of the color of the lamp, the color of high demand people choose a higher color temperature, requirements If you are not high, you can choose lower ones.
Three-color light tube is very popular for businesses to introduce three-color light tubes for eye protection products, Yang Zheng is very ridiculous. He introduced that all current energy-saving lamps are trichromatic lamps, but they have not heard which energy-saving lamps advertise themselves as eye-safe lamps. He said that although three-color light tubes do have better color reproduction than halogen lamps, their eye protection is only a selling point for business speculation.
Lin Yandan also stated that three-color light tubes have become very popular and most of the current workplaces use such tubes.
Doctors say that the light source is not the key to eye protection Tongren Hospital, deputy director of the Department of Ophthalmology doctor Chang Changbin introduced, as long as the light source brightness is sufficient, and relatively stable, do not have too much flash to meet the reading needs. Currently, the quality of table lamps that meet national standards is very reliable. They do not cause eye fatigue, cause myopia, or cause other damage to the eyes. Sui Changbin pointed out that the crux of what really causes young people's myopia is reading at a short distance, so the correct way to protect the eyesight is to reduce the reading time, take 10 minutes for every 30-40 minutes of reading, and maintain a correct reading and writing posture. He introduced that studies have shown that increasing extra-curricular activities and appropriately reducing reading time can effectively control the incidence of myopia in adolescents. At the same time, he believes that parents pay high prices for children to buy eye protection, be fooled by the business's flicker and speculation, and deviated from the true rules of eye protection.
