Many products on the market advertise as "eye protecting desk lamps", which makes consumers easily mistake the "product name" for the "function". In fact, "eye protection lamp" is just a common term, and the country has not issued specific standards for reading and writing desk lamps with eye protection functions, and the relationship between eye protection and desk lamp performance has not been rigorously demonstrated.

At present, the eye protection desk lamps on the market have another major selling point - "no flicker". The basic working principle of most eye protection lamps on the market is to increase the oscillation frequency of ordinary fluorescent lamps from low frequency flicker to high frequency flicker, so that the flicker cannot be distinguished by the naked eye. If high-frequency lamps are used at close range for a long time, it will actually have an impact on health.

Many consumers use "high brightness" as the standard when choosing a desk lamp, unaware that while the lamp greatly increases the illumination, the brightness of harmful reflections is also greatly increased, which can cause damage to the cornea, inhibit the function of retinal photoreceptor cells, and cause visual fatigue.
