What is the relationship between astigmatism and the appearance of the moon?

Astigmatism is a common eye condition that can affect how someone sees objects, including the moon. People with astigmatism may see the moon as blurry or distorted, with uneven edges or shapes. This is because astigmatism causes light entering the eye to be focused unevenly, leading to a distorted perception of objects, including celestial bodies like the moon.
