02. Myopia does not need to be cured, anyway, old to get presbyopia?
The eye is a complex instrument, just as The Newtonian system could not explain the theory of relativity. The pathogenesis of myopia and presbyopia is different, and it cannot be completely offset, it may only be a slight decrease in the degree of myopia, and it is more likely that there are both myopia and presbyopia, and it is not clear to see far and near.
03. Does high myopia cause blindness?
Myopia at 600 degrees and above is highly myopic. The eye axis of highly myopic eyes is longer than that of ordinary people, the pressure on the retina is very large, the retina is thinner than ordinary people, the probability of retinal cracks and detachment is higher than normal people, and the risk of glaucoma and cataracts is also greater, these diseases can lead to serious loss of vision or even blindness. There are not a few people who are blind due to ultra-high myopia.

yes! This is not a rumor. Senile cataracts are closely related to age, it appears because of the aging of the lens, the older the higher the incidence, aging and death are the destination of everyone, so no one can avoid senile cataracts. If you haven't developed senile cataracts, maybe it's just because you're not old enough.

With current technology, true myopia is incurable. After getting myopia, there are generally 3 choices: one is ordinary glasses and contact lenses, the other is orthokeratology lenses, worn when sleeping, you can see clearly without wearing glasses during the day, and the third is to do myopia surgery to completely bid farewell to the troubles of myopia and glasses.
However, these methods can not shorten the eye axis of myopia, not to cure myopia, but to help you see clearly again.
