Astigmatism of 50 degrees usually belongs to physiological astigmatism, which usually does not affect vision, so it does not need to be treated and does not require glasses. If astigmatism is present in your eyes, you should go to the hospital for a vision test to clarify whether astigmatism has affected your vision. If the astigmatism has affected the eyes, or the symptoms of eye fatigue, although the astigmatism is very small, it is recommended to wear glasses, not for a long time, but only when using the eyes, so as to reduce the symptoms of eye fatigue. Astigmatism is usually caused by an uneven cornea or unequal curvature of the cornea. If it is physiological astigmatism, it is also related to the gravitational effect of the eyelids.
