Eye Protection

Measures taken to prevent harm, damage, or injury to the eye.

Cornea

The transparent, front part of the eye responsible for focusing light into the eye.

Aqueous Humor

The clear, watery fluid in the front part of the eye that helps maintain the eye's shape and nourish the cornea and lens.

Vitreous Humor

The gel-like substance filling the back part of the eye that provides support to the retina.

Pupil

The adjustable opening in the center of the iris through which light enters the eye.

Zonula Ciliaris

A ring of fibers connecting the ciliary body to the lens, involved in adjusting the shape of the lens for focusing.

Sclera

The tough, white outer layer of the eye that maintains the eye's shape and provides protection.

Optic Nerve

The nerve that carries visual information from the retina to the brain.

Retina

The light-sensitive tissue lining the back of the eye that contains photoreceptor cells (rods and cones) converting light into nerve signals.

Rods

Photoreceptor cells in the retina responsible for vision in low-light conditions and detecting shades of gray.

Cones

Photoreceptor cells in the retina responsible for color vision and detecting fine details in bright light.

Blind Spot

The area on the retina where the optic nerve exits the eye, lacking photoreceptor cells, resulting in no vision at that point.

Tapetum

A reflective layer in the eyes of some animals that enhances low-light vision by reflecting light back through the retina.

Lens

A transparent, flexible structure in the eye that focuses light onto the retina by adjusting its shape.

Conjunctiva

The thin, transparent membrane covering the front of the eye and the inner surface of the eyelids.
