A gel-like substance that fills the eye's interior, helping it maintain its shape and providing optical clarity.
A transparent, flexible structure that changes shape to focus light onto the retina for clear vision.
Transparent, dome-shaped outer layer that refracts (bends) light to help focus it on the retina
The black opening in the center of the iris that allows light to enter the eye.
