Lens capsule
Lens Capsule
The Lens Capsule (pronounced: lenz kap-suhl) is a smooth, transparent, and elastic structure that encloses the lens of the eye. It is a component of the eye's anatomy that plays a crucial role in vision.
Etymology
The term "Lens Capsule" is derived from the Latin word "lens" meaning "lentil" due to the similarity in shape, and "capsula" meaning "small box", referring to its enclosing function.
Function
The Lens Capsule serves as a barrier, protecting the lens from any potential damage. It also holds the lens in place and helps maintain its shape for proper focusing of light onto the retina.
