晶状体 (jīng zhuàng tǐ)

noun HSK 6

Traditional 晶狀體

jīng zhuàng tǐ

lens (of the eye) · crystalline lens

Meaning

This is the medical and anatomical term for the lens inside the eye. The crystalline lens is a transparent, biconvex structure that helps focus light onto the retina. It's located behind the iris and pupil, and can change shape to adjust focus for near or far vision.

Usage

This is a technical medical term used primarily in healthcare, biology, and ophthalmology contexts. In everyday conversation, people rarely use this term unless discussing eye conditions like cataracts (白内障). Most laypeople would simply say 眼睛的镜头 or 眼球里的透镜 if they needed to refer to this structure in casual speech.
