1. Desk lamp with energy-saving lamp as light source.
Any use of energy-saving lamps as light sources, there will be strobe. Studies have shown that electromagnetic radiation and strobe are one of the biggest causes of myopia in young people.
2. A table lamp using a high-frequency electronic ballast.
With high-frequency electronic ballasts, strobes can't be felt by the eyes. However, it still exists in the form of waves. Moreover, the electromagnetic wave radiation emitted by high-frequency electronic ballasts will seriously damage the brains of developing children, as well as the retina.
3. The height of the table lamp should be greater than 40 cm.
If the height of the lamp is below 40 cm, flush with the human eye or slightly lower, it is easy to produce a large contrast between light and dark, so that the eye is constantly adjusting to adapt to the change of light and dark; at the same time, the structure of the lamp should properly block the side For strong light, when looking at the lamp at a height of 40 cm, the inner wall of the reflector and the light source should not be seen, otherwise it will cause glare. These are easy to cause visual fatigue, and long-term use will affect vision.
Sadly, in the eye protection market, manufacturers have produced a lot of cartoon small table lamps in order to cater to the cheapness of the picture, only for children to like, regardless of their health.
Therefore, it is recommended that parents should choose professional non-radiation and non-stroboscopic DC lamps when giving children special lamps. In this way, both strobe and high-frequency electromagnetic radiation are directly eliminated, and it is also highly suitable for children to use.
