First, the light should be sufficient to avoid reflection.

Comfortable light can get good visual information, and too strong or too dark light will bring bad effects to the eyes. Therefore, the desk where teenagers usually read books should have a side light device, with the purpose of reducing reflection and eye damage.

Second, continuous reading time should not be too long.

Teenagers read, write, watch TV and use the computer for hours without rest, and some students even go to bed late at night, which not only affects their health and makes their eyes overburdened, but also easily causes accommodative (or functional) myopia, that is, pseudomyopia. Moreover, the extraocular muscles will exert pressure on the scleral tissue of the eye wall, which will increase the intraocular pressure and make the intraocular tissue congested. Therefore, it is advisable for students to have a rest every 50 minutes when studying.

Third, the sitting posture should be correct and the distance should be moderate.

Don't hunch over, or read at your desk, let alone lie on the bed and read sideways. The distance between eyes and books should be 30-35cm, the distance between body and desk should be about10cm, and the angle between books and desk should be 30-45 degrees. If you put the book horizontally on the desktop, you should lean forward slightly when reading, so it is easy to move the book close to your eyes, which will increase the burden on your eyes by 2-3 times, thus causing fatigue of the neck muscles and the back of your neck. Unconsciously leaning forward for a long time will lead to decreased vision.

Fourth, watch less TV and use less computers.

Try to reduce contact with TV, computers, game machines and other electrical equipment that radiate to human eyes, because X-rays radiated by kinescope will consume rhodopsin in retina in large quantities, which can obviously reduce vision. It is best to use LCD as a computer to reduce the harm of electromagnetic waves to the eyes. Students who often play video games are more likely to damage their vision, while students with low vision who play video games since childhood can't even correct their vision with glasses because of the impaired function of retina and macula.

Fifth, get enough sleep and pay attention to eye hygiene.

Work and rest should be regular and get enough sleep. Lack of sleep can lead to conjunctival congestion, increased secretion, photophobia and tears, eye pain and other conjunctival and corneal inflammation. Should try to avoid sand, smoke, ultraviolet rays, infrared rays, chemicals, medical supplies and other injuries to the eyes. Personal hygiene should be kept clean, towels, washbasins, handkerchiefs and other personal items should be used by special personnel, and try not to use other people's items to avoid cross-infection, eye diseases and decreased vision.
