1, nearsighted people will still have presbyopia when they get old. Myopia and presbyopia have different pathogenesis and cannot be completely offset. It may be that the degree of myopia is slightly reduced, and it is more likely that they have myopia and presbyopia at the same time. It is not clear whether they are far or near.
2, low myopia also needs glasses. If low myopia affects vision, you need glasses, otherwise it will easily lead to visual fatigue and deepen the degree. If myopia is below 300 degrees, wear it at a distance, but not at a close distance. There are more than 300 nearsightedness, and you need to wear it often when you look far and near.
True myopia can only be corrected. After myopia cannot be cured, there are generally three choices: one is ordinary frame glasses and contact lenses, and the other is orthokeratology glasses, which can be worn when sleeping and can be seen clearly without glasses during the day. The third is to do myopia surgery and bid farewell to the troubles of myopia and glasses. However, none of these methods can shorten the axial length of myopia, not to cure myopia, but to help you see clearly again. With current technology, true myopia cannot be cured.
4. Senile cataract is closely related to age. Senile cataract is closely related to age. It appears because the lens is aging. The older you get, the higher the incidence.

Blindness in the late stage of diabetes is not a bluff. Therefore, it is recommended to check your eyes once a year after you have diabetes.
6. High myopia has the risk of blindness. Myopia above 600 degrees belongs to high myopia. The axial length of high myopia is longer than that of ordinary people and the retina is thinner than that of ordinary people. The probability of retinal tear and detachment is higher than that of normal people, and the risk of glaucoma and cataract is also greater. These diseases may lead to severe vision loss or even blindness. There are not a few people who are blind because of ultra-high myopia.
7, wearing glasses can not control the degree of growth can not! Because glasses are crutches, the main purpose of wearing glasses is to see things clearly and reduce eye fatigue. After wearing glasses, the degree will develop and change with the lack of eye habits, eye habits and eye anti-fatigue ability. It is normal for the degree to increase by about 100 degrees every year. There are also examples of good eye habits, which will be stable at a certain degree for a long time. Pay attention to eye hygiene in daily life, insist on doing eye exercises, and eat more foods containing vitamins A and B 1 such as vegetables. Don't get too close to read, write, watch TV or computer. Relax your eyes every 45 minutes 10 minutes, and check your eyesight regularly.
