Myopia and astigmatism of over 100 degrees require correction with eyeglasses. The severity of myopia and astigmatism is expressed in degrees, with higher degrees indicating greater severity and greater impact on vision. Pseudomyopia or astigmatism of more than 100 degrees can be corrected without eyeglasses, and the transformation of pseudomyopia into true myopia can be slowed down and prevented by practicing good eye habits. True myopia and astigmatism of more than 100 degrees have already caused more obvious effects on vision, and should be corrected by wearing eyeglasses. Otherwise, it is easy to cause visual fatigue because of the lack of clarity, which will accelerate the growth of myopia and astigmatism. If you have any symptoms of eye discomfort, you should go to the ophthalmology department of the hospital in time and consult the ophthalmologist for guidance.
