Crystalline Lens (Noun)
Meaning
Biconvex transparent body situated behind the iris in the eye; its role (along with the cornea) is to focus light on the retina.
Classification
Nouns denoting body parts.
Examples
- The crystalline lens in the human eye changes shape to adjust focus on objects at varying distances.
- By flexing the ciliary muscles, the shape of the crystalline lens can be altered to accommodate differences in focal length.
- A normal crystalline lens has the unique ability to refract, or bend light as it enters, helping us to clearly see the objects around us.
- In individuals with cataracts, the clear and transparent crystalline lens has become cloudy, interfering with the normal passage of light into the eye.
- When light enters the eye through the cornea, it is further refracted by the crystalline lens and directed onto the retina at the back of the eye.
