When are the eyes set and when are the human eyes set?

Analysis:

Generally at the age of 6 to 8 years, the visual system will develop to a normal level and mature around the age of 20. If the degree of myopia continues to deepen in adulthood, on the one hand, it is a problem with the eyes themselves, that is, pathological myopia; On the other hand, it is still caused by bad eye habits, which are mainly manifested in eye abuse, such as surfing the Internet all night, playing video games, etc. Wrong eye habits can not only deepen myopia, but also induce eye diseases such as acute attacks of glaucoma, chronic conjunctivitis, and central serous chorioretinopathy.

Therefore, eye maintenance is lifelong, and regular check-ups are required even after vision is stable, for example, a health check-up once a year is an opportunity to maintain your eyes.

Guidance: No, eyes need to be maintained for life, not for a certain age group, even if they are in their 20s or 40s. If an adult reads a book, watches a computer and TV for a long time, causing the eyes to be in a state of fatigue for a long time, vision will also be affected. In fact, for immature children, when there is a problem with the eyes, everyone will actively take measures to prevent the deterioration of vision, but as people get older, people's worries about vision problems will gradually disappear, and vision protection measures will be weakened.

The reason for this is that many patients think that the eyes are "stereotyped" in adulthood, and it is unlikely that they will change again, and they do not need to pay attention to maintenance, which is wrong.

Life care: We must advocate "saving eyes".The time spent looking at nearby things should not exceed 6 hours a day; If reading, writing, looking at the computer, etc. exceeds 40 minutes, you need to take a break of 10 to 15 minutes; When operating a computer, keep your eyes at least 60 cm away from the computer screen; If the desk lamp for reading is an incandescent lamp, it is best to be 25 watts, and the light should not be directly exposed to the eyes; Participate in outdoor sports. If you have dry eyes, redness, or a foreign body sensation, you should close your eyes for a few minutes and apply a warm compress to your eyes with a hot and humid towel to relieve visual fatigue.

The age of eye stereotyping usually refers to after the age of 18, that is, after the end of the third year of high school, which is generally a vague value. Not everyone does not have an eye power after the age of 18, and the eye axis is not elongated, which refers to the number of high probability statistics. Most people basically stabilize their myopia after the age of 18 and do not grow, but a very small number of people or patients with high myopia have no age limit for eye stereotyping.

High myopia has a certain relationship with genetics, it is growing every year, not after the age of 18, or with age, the eye axis will gradually lengthen. So the degree of myopia will be more than 600 degrees, or even 700-800 degrees, and it will increase every year.
