How it's used
Refers specifically to the refractive error of the eye where the cornea or lens is irregularly shaped. It is frequently mentioned alongside 近視 when discussing vision problems or prescription strength. Opticians often use this term when explaining why a person might still see blurry images despite having clear vision for distant objects.
Examples
My eye has two hundred degrees of astigmatism.
Have you gone to get a pair of glasses for astigmatism?

Common mistake
Do not confuse this with 閃光, which refers to a flash of light or glare. Beginners sometimes mispronounce the tone, leading to confusion between the medical condition and the visual phenomenon.
