What does astigmatism mean?
A vision condition in which the eye's cornea or lens cannot focus light evenly onto the retina, resulting in distorted or blurred vision. It can be caused by an irregularly shaped cornea or lens.
Example
"The optometrist diagnosed the patient with astigmatism and prescribed corrective lenses to improve their vision."
