What protects our eyes?

Answer 1

What protects our eyes?

There are several mechanisms designed to protect our eyes from external damages and pathogens. First is the conjunctiva, a thin, clear membrane covering the front of the eye and inner eyelids. Cells in conjunctiva produce a mucous that helps to lubricate the eye.

Our eyelashes and eyebrows are specialized hairs to protect the eyes from particles that may injure them. Anything touching them triggers the eyelids to blink. Our eyelids protect and lubricate our eyes.

Small oil-producing glands line the inner edge of our eyelids. These oils mix with tears when we blink, keeping the eye moist and clean. The orbit or eye socket is a cone-shaped bony cavity that protects the eye. The socket is padded with fatty tissue that allows the eye to move easily. The Lacrimal Gland continually releases tears and other protective fluids onto the surface of the eye to keep the cornea from becoming dehydrated.

The iris helps protect the sensitive retina by opening and closing the pupil, in response to the brightness of surrounding light. Finally, there is sclera, the white, tough wall of the eye. It along with internal fluid pressure keeps the eye shape and protects its delicate internal parts.

Answer 3

This is a good question to ask. There is a basic Science involved in this. There are several ways to protect our eyes. Some of them are :

Wear Sun glasses to protect eyes from sunlight
Wash your daily with clean water three to four times
Do not read while travelling
Do not read with your books very close to your eyes while reading
Put some honey or drops to clear off the dust particles from your eyes
Put cotton buds on your eyes by wetting it into milk to cool them

Answer 4

In many animals, including humans, eyelids wipe the eye and prevent dehydration. They spread tears on the eyes, which contains substances which help fight bacterial infection as part of the immune system. Some aquatic animals have a second eyelid in each eye which refracts the light and helps them see clearly both above and below water. Most creatures will automatically react to a threat to its eyes (such as an object moving straight at the eye, or a bright light) by covering the eyes, and/or by turning the eyes away from the threat. Blinking the eyes is, of course, also a reflex.

In many animals, including humans, eyelashes prevent fine particles from entering the eye. Fine particles can be bacteria, but also simple dust which can cause irritation of the eye, and lead to tears and subsequent blurred vision.

Answer 5

Eye needs to be protected from(1) dust, bacteria etc, and(2) the intensity of light.
For the first, there are eyelashes, eyelids and sebaceous gland producing sty which is bacteriostatic, and most importantly, lachrymal glad that secretes tears which contains lysozyme to damage bacterial wall. Tears has an antiseptic property
For the second, there is iris which through expansion and contraction controls the amount to light to fall on the retina.

Don't rub them or pull them, If you wake up and you have that nasty dried stuff just take a warm wet rag and gently rub, it'll remove it and keep your eyelashes in contact
