Eye protection may not be eye-protected
Do you know the myopia rate of primary and secondary school students? In recent years, the ageing of myopia has become a common fact. The increasing number of myopia among primary and secondary school students has ruined many parents. Therefore, many businesses have seized the psychology of parents and have launched a so-called "eye-protection lamp" with the concept of "effective prevention of myopia". At the beginning of the new semester, the enthusiasm of parents to buy eye-protection lamps is growing, and many parents are willing to pay for expensive eye-protection lamps. however,
Is the eye protection lamp on the market really effective? Can eye protection really prevent myopia?
Questioning the eye-protection lamp to make the child's vision drop
Recently, Nanchang citizen Ms. Yang said that in the first half of this year, she bought an eye-protection lamp because it claimed to be "effective in preventing myopia". She loved her son and spent 169 yuan to buy a son who was facing the senior high school entrance examination. Hey. Unexpectedly, she spent "big price" and did not "buy" to get good results. After a few months, her son always said that his eyes were uncomfortable, and his eyesight was not as good as before. After optometry, my son's myopia deepened.
Ms. Yang said that after listening to the professional introduction, the eye-protection lamp claimed to prevent myopia, but the stroboscopic frequency was increased, and the eye could not feel the flashing of the light. At the same time as the high frequency was generated, the lamp would generate electromagnetic radiation. Harm to human health. Ms. Yang is very worried about this. “Since eye protection can't prevent myopia, it will aggravate myopia. Is the promotion of 'effective prevention of myopia' not a lie?â€
Most of the merchants in the lighting market are promoting the efficacy of eye protection to prevent myopia.
Many lighting store businesses have placed eye-protection lights in the eye-catching position of the store. Ordinary, oxygen bar, cartoon... dazzling. In a shop called "New Star Lighting", "Liang Liang" brand eye protection lamp produced by "Shanghai Liangliang Lighting & Electric Co., Ltd." was said by the clerk to be "small and sloppy". However, the implementation standard of this product is GB7000.1-2002 ("General Safety Requirements and Tests for Luminaires").
It is understood that the price of eye protection lamps varies greatly. The low-priced eye-protection lamp has a rough workmanship, a high-priced appearance, and a brighter light. It is said to have functions such as noiselessness and oxygen bar, which are favored by consumers. However, the implementation standards for the packaging of multiple brands of eye-protection lamps are GB7000.11-1999 ("Safety Requirements for Portable General Lamps").
In a supermarket, “Shenshibao†eye-protection lamp produced by “Shenzhen Jianzhijia Industrial Development Co., Ltd.†also wrote a slogan to prevent myopia on its outer packaging, and also wrote “To be eyesight†Well, use the child as a treasure, and other statements that clearly mislead consumers. However, the product implementation standards of “Child Vision†are GB7000.1-2000, GB7000.11-1999, and GB17743-1999.
Although many eye-protection lamps claim "natural light", "no radiation", "can effectively protect eyesight", in the product packaging, there is no department that can prove the eye-protection lamp "natural light", "no radiation", "can Test report for protecting vision.
Investigate the implementation of common lighting standards
What kind of products does the eye protection lamp belong to? Secretary-General Xu of Jiangxi Household Appliances Maintenance Association said that eye-protection lamps are one of the lighting products and belong to household appliances. The production of lamps is a “3C†that must comply with the national electrical and electronic products safety certification. Propaganda like eye protection can prevent myopia. If you improve your eyesight, it will involve the efficacy of the product. It must be tested by the relevant state departments. This can only be promoted after the relevant certification materials are issued. Otherwise, it is to exaggerate the efficacy of the product and deceive the consumer.
At the same time, Secretary Xu said that the eye-protection lamp is a functional type lamp, and at least the product description should indicate the principle of eye protection, the relevant test report of the national authority or the effect of clinical experiment.
Appliance Maintenance Association eye protection lamps need to test report
Is there any scientific basis for eye protection? Why are the manufacturers that produce eye-protection lamps different in terms of product standards? The staff of the surname of the surviving bureau of the Jiangxi Provincial Quality Supervision Bureau said that the current national standards for eye protection have not been established, so there have been different standards implemented by manufacturers.
According to reports, there are three mandatory standards for the national standards for lamps implemented in China. However, these can only be regarded as the implementation standards for ordinary lamps. The specific eye protection lamp, the standard has not been implemented. Then, can the lamps produced according to the safety standards of ordinary lamps have the function of preventing myopia? Can not help but question.
According to the staff of the quality supervision department, the eye-protection lamp on the market only improves the stroboscopic frequency through the high-frequency electronic ballast. Its working characteristics and working mode are completely consistent with the energy-saving lamps.
Quality supervision countries have not yet established relevant standards
Shanghai eye protection rate is only 53.3% (related information)
According to the Shanghai Municipal Administration for Industry and Commerce, the quality of the eye-protected table lamp sold on the Shanghai market is only 53.3%.
The monitoring collected a total of 30 kinds of commodities distributed by 13 large supermarkets or department stores, involving 13 inspection items. The unqualified items mainly focused on disturbance voltage, illumination on the table, durability test and product identification.
First, the disturbance voltage exceeds the limits specified in the standard. If the disturbance voltage of the luminaire exceeds the limit, it will affect the normal operation of the broadcast TV receiver and instrumentation equipment around it, resulting in failure to listen to the monitor or malfunction of the instrument.
Second, the illumination on the desktop is not up to standard. According to the product standard, the desk lamp for writing lighting should provide sufficient illumination and illumination uniformity on the desktop in the normal working position, so that the human eye feels comfortable and is not prone to fatigue.
Third, the durability test failed. When working under normal conditions and abnormal conditions, the lamp parts should not be damaged prematurely, nor should there be unsafe phenomena such as burnt deformation.
Fourth, the product identification is unqualified. The monitoring found that the single failure rate reached 66.7%.
The industry and commerce department reminds consumers that there is no relevant research report on the relationship between lighting quality and protection of vision. There is no scientific basis for the "eye protection table lamp", and more for commercial propaganda purposes. Don't trust it.
