When your nearsightedness is less than 200 degrees, consider wearing glasses only when you look far away.
And when you are more than 300 degrees, especially more than 600 degrees, it is better to always wear glasses, otherwise it will easily cause eye fatigue and deepen myopia.
People who don't wear glasses often use blinks, hoes, frowns, etc. to make up for the lack of vision. This will not only increase the depth, but also the small wrinkles in the corners of the eyes.
In general, myopia increases by an average of 300 degrees, and the length of the eye axis increases by 1 mm.
Therefore, people with high myopia, especially those with more than 1000 degrees, will have a much longer axis of eyesight than the average person. The more uncoordinated the ratio, the more attractive the eye looks, and it has nothing to do with glasses.
