Example

She was diagnosed with astigmatism and needed glasses to see clearly.

Conversation

I just found out I have astigmatism in my left eye.

Oh really? That sounds frustrating!

Yeah, it explains why I've been seeing things a bit blurry lately.

I can imagine! Have you talked to an eye doctor about it?

Synonyms & Antonyms

Root Explanation

Astigmatism is formed from "a-" (meaning without) and "stigmatismos" (from Greek "stigma", meaning point or mark). The term describes a condition where the eye does not focus light evenly, resulting in distorted or blurred vision, hence the absence of a clear point of focus.

Memory Tip

Think of 'without' ('a-') a clear 'point' ('stigma') of focus — that's what astigmatism means.
