Is optical illusion related with the astigmatism?

Answer 1

Optical illusions and astigmatism are not directly related, but they can interact with each other. Optical illusions are visual phenomena that trick the brain's perception, while astigmatism is a common refractive error caused by an irregular shape of the cornea or lens, leading to blurred vision. While astigmatism can affect how one perceives certain images, making some optical illusions less effective or distorted, the illusions themselves are primarily psychological and do not depend on any vision defects.
