Eye Lens (Crystalline Lens): What It Is, Anatomy & Function
网页2024年8月13日 · The lens is a clear, curved structure that’s embedded deep within your eye (or camera). It absorbs light and bends it to converge at a single point behind it. This focuses the light for the sensors at the back — whether that’s camera film, digital sensors or, in your eye, the retina.

网页2017年8月15日 · The lens can change shape with the aid of the ciliary muscles, thereby changing the focal distance to the retina and bringing the image into sharp focus on the retina. This adjustment of the lens is known as accommodation (similar to the focusing of a photographic camera via movement of its lenses).

网页2024年5月11日 · The crystalline lens is a convex lens that creates an inverted image focused on the retina. The brain flips the image back to normal to create what you see around you. In a process called accommodation, the elasticity of the crystalline lens allows you to focus on images at far distances and near with minimal disruption.
