cornea-This dome-shaped layer protects your eye from elements that could cause damage to the inner parts of the eye.
pupil-This black area is actually a hole that takes in light so the eye can focus on the objects in front of it.
lens-This is a clear layer that focuses the light the pupil takes in
vitreous-The vitreous humor is the gel located in the back of the eye which helps it hold its shape.
sclera-The sclera provides structure and safety for the inner workings of the eye, but is also flexible so that the eye can move to seek out objects as necessary.
retina-The retina is located in the back of the eye, and is connected to the optic nerves that will transmit the images the eye sees to the brain so they can be interpreted.
