Vitreous Humor
Supports the globe of the eye and maintains its shape.
Aqueous Humor
Provides nutrients to the eye and maintains intraocular pressure.
Sclera
Protects the inner components of the eye and provides attachment for extraocular muscles.
Ciliary Body
Produces aqueous humor and involves in the eye's accommodation reflex by altering the shape of the lens.
Pupil
Allows light to enter the eye and reach the lens and retina.
Rod Cells
Provide vision in low light conditions and peripheral vision.
Choroid
Provides blood supply to the eye and absorbs stray light to prevent reflections.
Retina
Contains photoreceptors that convert light into electrical signals.
Optic Nerve
Transmits visual information from the retina to the brain.
Lens
Fine-tunes light focusing onto the retina.
Fovea Centralis
Provides the sharpest vision due to high concentration of cone cells.
Cone Cells
Responsible for color vision and visual acuity.
Cornea
Refracts light to help focus it onto the retina.
Macula
Responsible for central vision and high-resolution color vision.
Iris
Regulates the diameter of the pupil and thus the amount of light reaching the retina.
