There are a lot of LED reading lamps on the market. Are they really "protecting the eyes" as advertised in their advertisements? Some experts pointed out that the quality of LED reading lamps on the market is currently uneven, and many LED reading lamps do not protect the eyes. It is reported that the quality of LED table lamps on the market is uneven. Since most of these lamps use low-power LEDs as the light source, their total power is insufficient to achieve sufficient illumination. In addition, these LED desk lamps have no effect on eye hygiene, depending on their function. If it is used as a bedside lamp or a night light, the control requirements are not high, and the impact may be small; however, if it is used as a reading lamp, insufficient illumination will accelerate visual fatigue and is not conducive to protecting vision. So, what should the people pay attention to when buying reading lamps? Associate Professor Lin Yandan from the Institute of Light Sources and Lighting Engineering, School of Information, Fudan University, pointed out: “Firstly, we must observe whether the distribution of the spot emitted by the product itself is uniform; secondly, don’t feel particularly dark, this is the average illumination is not enough; in addition, write under the lamp When things are, I feel that the lights are not directly punctured to the eyes; there is also a natural light, not to be white." In addition, experts pointed out that ordinary consumers do not have the professional knowledge and specialized measuring instruments when purchasing reading lamps. The performance of reading lamps can only be known from the product identification and observation effects. Therefore, it is recommended to purchase formalized certified products through formal channels to prevent some bad products from being shoddy. It is understood that according to the transformation plan formulated by the Institute of Electric Light Sources of Fudan University, more than 40,000 classrooms in Shanghai have completed the transformation of the light environment. According to the vision tracking of the relevant health departments and ophthalmology departments commissioned by the Shanghai Municipal Education Commission for three years, this move is conducive to inhibiting the occurrence of myopia in primary and secondary school students in Shanghai.
