Quick Answer:

Astigmatism is the correct medical term for a common eye condition that causes blurred vision. Stigmatism is usually a mistaken shortening of the word and is not the standard medical term.

Have you ever searched online for blurry vision and found both stigmatism and astigmatism? Many people do. A person may visit an eye doctor, hear the diagnosis, and later try to remember the word. When they search online, they often type “stigmatism” instead of “astigmatism.”

This confusion is very common because the two words sound similar. In everyday speech, some people drop the first part of the word and say “stigmatism.” However, eye doctors, medical books, and health websites use the word “astigmatism.”
