If the degree is too low, the light on the book is dark, we can not easily see the writing, which will cause visual fatigue, and long time will lead to myopia.

If the desk lamp is too low, it will cause the light to be too small and the surroundings will be dark. Losing the reference object for the distant vision, the eye adjustment system is in a tight compression state that only looks close, and it is easy to make the eyes fatigue and accumulate rapidly, resulting in 'light source myopia'. If the desk lamp is too high, the light will directly shine into our eyes and produce glare. At the same time, close-range glare will cause light retention on the retina, which will make the eye muscles tighten and speed up vision loss.

The placement of the desk lamp also has a great influence on vision. Because most people write with their right hand, the desk lamp should be placed on the left front of the body.

Glare can cause difficulties in our reading, and it can easily cause discomfort such as eye fatigue, soreness, or headache. When the indoor main lamp and the table lamp are too bright, the glare will also occur. In addition, it is necessary to use the space lighting or ambient lighting in addition to the desk, using three levels of light source to reduce the contrast with the environment, is also a way to prevent eye fatigue.
