Generally speaking, simple low-grade regular astigmatism may require wearing children's glasses, while low-grade irregular astigmatism requires long-term wearing of glasses, otherwise, it can easily induce visual fatigue, causing discomfort symptoms and inability to work at close range for a long time.
Astigmatism refers to astigmatism where the refractive power in the vertical direction of the eyeball is greater than that in the horizontal direction; The refractive power in the horizontal direction is greater than that in the vertical direction, which is called inverse astigmatism.
The visual acuity of astigmatic eyes is closely related to the degree and nature of astigmatism. Low-degree astigmatism generally does not affect visual acuity, while moderate astigmatism can cause poor near and far vision. Reverse astigmatism has a greater impact on visual quality, while forward astigmatism has a smaller impact.
So, whether low refractive errors should be worn for a long time depends on the condition of the eyes of children glasses, rather than whether you will look at you again after shooting in physical education class.
Understand how people usually feel when they don't want to wear glasses, after all, there is always something hanging on their nose bridge, which is somewhat annoying. Regarding this issue, there is only one type of myopic patient who does not need to wear glasses for a long time.
That is the population with mild myopia, that is, patients with myopia degrees less than 300 degrees. When looking at a computer in a normal sitting position at close range, if you can easily and comfortably see clearly, you can consider not wearing it.
But at other times, it is still recommended to wear childrens glasses. (What should I do with my classmate who has moderate to high myopia? Please, what can you see clearly without glasses...)
