How are the eyes protected?
- Eye socket: Depressions in the skull
- External eye muscles: Fix the eyeballs in the orbit.
- Eyebrow: The eyebrows act as a shield to keep dirt, sweat, and other debris from entering the eyes. They also help keep the eyelashes from rubbing against the eyes. Eyebrows also provide a physical barrier against the sun’s UV rays, helping to protect the delicate skin around the eyes.
- Eyelashes : The eyelashes help to keep dust, pollen, and other debris from entering the eyes by trapping them in their hairs. They also help to keep sweat from dripping into the eyes, and can help protect against injury from small objects.
- Eyelids: The eyelids help to keep the eyes moisturized by producing tears. They also protect the eyes from bright light by providing a physical barrier.
- Conjunctiva: The conjunctiva is a thin, transparent membrane that covers the inner surface of the eyelids and the outer surface of the white of the eye. It helps to keep the eye lubricated and protects it from bacteria, dust, and other foreign particles.
- Tears: Tears are made up of water, oil, and mucus and they provide a protective layer that helps to keep the eyes moist, thus reducing the risk of infection. Tears also contain antibodies that help to fight bacteria and other microorganisms that can cause eye infections. Additionally, tears can help to flush out dust, dirt, and other debris that can enter the eye and cause irritation.
