It is well known that many factors influence the occurrence of shortness of vision, especially in adolescents. Numerous factors can contribute to its emergence and progression. Working on proximity, learning or reading at low light, etc. We know that students and people who read a lot spend most of their time in close proximity. What techniques of prevention do you know?
Nearsightedness (myopia) is the most common visual disorder among young people. An excessively long eyeball (Figure) results in the focal point falling in front of the retina. Consequently, distant objects appear indistinct, while nearby objects appear sharp. Myopia is treated using concave glasses lenses or contact lenses and in selected cases can be corrected surgically. Surgery alters optical factors but not the length of the eyeball. Myopia usually begins at elementary school age, and progression usually ends after puberty. Continued progression after the age of 25 years is exceptional.

Thank you Mostafa Madmoli to contribute to and clarify the meaning of myopia. Can we prevent it and in what way?

YES....I guess it is to some extent treatable....but not my domain to comment further
Many childhood myopia in developing countries remained undetected and untreated, especially at early stage. Public health program for screening and treatment may be useful to avoid complications. Please read the cited references:-

We can certainly reduce the progression of myopia. See the papers mentioned above.
The latest approach is to increase outdoor activity and walking on a fresh air
Myopia has increased worldwide during recent years and is becoming a serious public health problem. In East Asia, the prevalence can reach 80% of the population. The focus for screening and interventions should be on early life during childhood when myopia progression is faster. Review and discussion of the recent literature on potential interventions for preventing the development of myopia or slowing its progression. Increased time spent outdoors is a protective factor for myopia progression. Undercorrection increased myopia progression and optimal correction is mandatory. The use of progressive or bifocal lenses (spectacles or contact lenses) may yield a slowing of myopia by limiting eye accommodation. Rigid gas permeable contact lenses were found to have few effects on myopic eye growth. A marked slowing of myopia was observed with orthokeratology by temporarily changing the curvature radius of the cornea. The largest positive effects for slowing myopia progression were observed with atropine eyedrops with an interesting dose effect. The benefit of surgical scleral reinforcement is reserved for severe and progressive myopia.
if memory serves myopia can also be caused by modern technology, and there was a study done a number years ago which showed repeated use of a computer can cause visual issues in the younger generation.
in terms of avoidance regular breaks away from phones, computers etc can reduce the damage to the eye, and can therefore possibly reduce myopia. this is opinion only as I am unable to find the study at this time
