Explore eye anatomy from cornea to optic nerve, learn how the pupil and lens focus light, and connect structure to everyday vision: sports tracking, photography, night driving, and screens.
What you’ll learn
The cornea and lens bend light; the iris controls pupil size to regulate how much light reaches the retina.
Aqueous Humor fills the front chamber; Vitreous Humor is the gel behind the lens that helps the eye keep its shape.
The retina contains rods and cones; the optic nerve sends signals to the brain, where you perceive images.
Extraocular muscles such as rectus muscles move the eye; eyelids and tears protect the surface.
Accommodation changes lens shape so you can focus on near and far objects.
