Structures that provide protection, lubrication, and support to the eye.

Skin continuation that protects the eye; helps keep it lubricated and clean through blinking.

The gap between the upper and lower eyelids.

Mucous membrane that covers the inner surface of the eyelids and the anterior surface of the eyeball.

System responsible for producing, distributing, and removing tears from the eye.

Gland that produces tears to cover the conjunctiva and contains antibacterial enzymes.

Liquid produced by the lacrimal gland that keeps the eye moist and helps with hygiene.

Transparent part of the outer layer of the eye that allows light to enter.

Layers of the eyeball's wall: outer fibrous layer, intermediate vascular layer (uvea), and inner layer (retina).

Vision impairment in low light due to vitamin A deficiency.

Condition where visual pigments are fully receptive to low light.

State where visual pigments are balanced between bleaching and reassembly in bright light.

Neurons that relay visual information from the retina to the brain.

Point where optic nerves partially cross each other before reaching the brain.

Ability to judge distances between objects based on images from both eyes.

The larger compartment in the eye behind the lens.

The smaller compartment in the front of the eye, divided into chambers.

Fluid circulating in the anterior cavity, maintaining eye shape.

The pressure created by aqueous humor in the eye.

A condition characterized by elevated intra-ocular pressure.

The gel-like substance filling the posterior cavity of the eye.

Loss of transparency or cloudiness in the lens of the eye.

Enucleated cells in the lens that contain crystallins for clarity.

The point where light rays converge on the retina.

A condition where light is not refracted properly, causing distorted vision.

Image on the retina is miniaturized and upside down, reversed left-right.

Clarity of vision, commonly rated as 20/20.

An abnormal, permanent blind spot in vision.

Normal vision with no refractive error.

Nearsightedness; difficulty seeing distant objects.

Farsightedness; difficulty seeing nearby objects.

Cells in the retina that detect light: rods and cones.

Ability to perceive different colors using cones.

Inability to distinguish certain colors.

Series of steps transforming light into neural signals.

The front part of the eye filled with aqueous humor.

The larger area in the eye filled with vitreous body.

The outermost layer of the eyeball consisting of the sclera and cornea.

The white part of the eye, part of the fibrous layer.

The colored part of the eye that controls the pupil's size.

Structure that connects the iris to the lens and controls the shape of the lens.

Photoreceptors for black, white, and gray vision; sensitive to light.

The origin of the optic nerve, known as the blind spot.
