I suggest you study the causes of myopia and how to prevent it from deepening. I think this is the most important thing.
Astigmatism includes myopia astigmatism and hyperopia astigmatism, both of which belong to ametropia. All objects seen by people with ametropia will not fall on our retina, and they need to adjust their eyes as close as possible to the retina, but some people will never be able to transfer to the retina.
So we can only help them through lenses, and astigmatism is also included.
After wearing glasses, the imaging naturally falls on the retina, and there is no extra adjustment or mediation for the eyes, so small that it does not affect the fatigue of the eyes.
He is just a tool. Whether you can wear glasses has nothing to do with tools or whether you can wear glasses in the future.
The degree of deepening is closely related to your eye habits, close eye use time, sitting posture and so on. If you don't pay attention to those, your eyesight will be poor if you take off your glasses, so you can't go on as you are worried, can you?
If you know the root cause, put on glasses to relax your child's eyes, and then control the stability of the degree. /kloc-after 0/6 years old, children's eyeballs are well controlled after they develop and take shape. If he is still at that astigmatism, he doesn't need to wear glasses. You can wear it when you need it, you can take it when you don't need it, and it won't affect his diopter.
Because the eyeball is developing now, if high tension is adjusted every day, it will only aggravate the degree of eye fatigue, lead to higher and higher degrees, and will also affect the development of children's stereoscopic fusion function.
