Some researchers said that by observing the EEG, it was found that even if the stroboscopic flash speed in the environment was too fast for people to notice, the retina of the organism could still distinguish the light with the frequency of 100- 160Hz, or even as high as 200Hz, and react. In the animal experiments represented by cats, the light with the frequency of 100- 120Hz has caused its brain cells.

May affect reading and vision.
Studies have shown that the frequency flicker of fluorescent lamps and CRT screens will affect people's eye movements when reading words. In addition, in some health examination reports, it is also found that the visual impairment is caused by the frequency flicker of fluorescent lamps.

May induce migraine
Experiments show that the stroboscopic frequency of 100Hz fluorescent lamp may double the incidence of headache among office workers. Of course, this effect is usually considered as a special case, which only happens in special people.

Reduce work efficiency and cause work-related injuries
In light industry, food, printing, electronics, textile and other industries, straight fluorescent lamps are widely used in lighting fields, such as assembly lines. Visual fatigue and migraine caused by stroboscopic lighting will cause difficulties in positioning and low production efficiency. In machinery industry, such as crane operators, visual fatigue caused by stroboscopic will cause positioning difficulties, operational errors and even accidents; When the speed of the moving object is multiple to the stroboscopic frequency of the light source, the moving state of the moving object will produce the illusion of static, backward and slow, which is easy to cause industrial accidents.
