Three hazards of eye protection lamps
Does eye protection lamps have the function of preventing myopia?
I have seen in some markets that some sellers have been promoting another major effect of eye protection lamps ‘prevention of myopia’. If the eye protection lamp has the function of preventing myopia, then this does not belong to the category of lighting fixtures, which should belong to medical equipment. And if the eye protection lamp really has this effect, then the eye protection lamp should go through a series of clinical trials and be reported to the relevant departments for approval before it can be marketed. At present, there is still no relevant authority of the department to confirm that the eye protection lamp has the effect of preventing myopia, so these behaviors of some businesses are irresponsible, and I hope that consumers can correctly understand these things.
Today I will share with you some hazards of eye protection lamps and some disadvantages for consumers. Anything must be viewed in two parts. A thing has both a good side and a bad side as well.
1. The biggest harmful electromagnetic radiation of eye protection lamp
The biggest advantage of eye protection lamp is that the light is stable, giving people a more comfortable lighting environment. The basic application principle of eye protection lamps is to use high-frequency electronic rectifiers to adjust the frequency of the current to several kilohertz or even tens of thousands, while some ordinary lighting fixtures are 50 Hz. That is to say, the flashing frequency of the eye protection lamp is already beyond the response of the nerves of our eyes. It is equivalent to a slow-moving bicycle. We can see the condition of every spoke of it, but when the speed of the vehicle reaches a certain speed, we can see it. To a circle, we can’t see the case of the spokes. It is true that this high frequency electronic rectifier also brings a problem, it produces high frequency electronic radiation. Everyone knows that high-frequency electronic radiation is harmful, especially for adolescents in the developmental period. Just like some parents do not let children use mobile phones, in fact, the electronic radiation of this eye protection lamp is more serious than the radiation of mobile phones, so we are in When using the eye protection lamp, you need to pay attention to let the child use it in less amount, and pay attention to protect yourself when using it!
2. The light of the eye protection lamp is too strong, long-term exposure to this light will cause visual fatigue and decline
The current market for eye protection lamps The light tubes are all fluorescent tubes, and most of the light emitted by the fluorescent tubes is white. When we study or work in this light for more than 15 minutes, we will feel tired. This is because our eyes can accept yellow light, which is why we feel more comfortable reading and studying under yellow light. Maybe some consumers say the yellow light emitted by the eye protection lamp at home! In fact, this is an illusion. It is a yellow substance smeared inside the lamp tube, and the light emitted by the light source is actually white light!
3. The eye protection lamp has ultraviolet radiation, which will cause certain damage to the skin and eyes
We have shared with you most of the current lamps They are all fluorescent tubes as the light source, and this kind of fluorescent lamp needs to excite the phosphor powder to generate the light source. Remember that there are many ultraviolet disinfection lamps on the market, in fact, they use this principle. Then you may think why the fluorescent lamps we usually use are not harmful to our skin? This is because we are usually far away from fluorescent lamps (usually two meters away), and the use of eye protection lamps requires close use. Therefore, children at home must try to stay as far away as possible when using eye protection lamps. I remember there was a report that long-term exposure to ultraviolet rays would damage the retina to a certain extent, and even severely affect the eyesight and cause blindness!
