Why do you blink both eyes?

Answer 1

Blinking is an instinctive action that can be voluntarily controlled.

There are two reasons we blink. One is that tear drops are used to keep the eyes from drying out. The second is a reaction to an approaching object, shutting the eyes so they aren't injured.

For the physiological mechanism of blinking, see the related link.

Answer 2

Sometimes, your eyes will blink because they just saw a hideous person, or blinking may also result if soemone throws a biddly bong pill directly into your eyeball cavity. Upon contact from pill to eyeball you must scream BUNMORE FOR BRIAN really loudly so all can hear, this will help shake the pill loose or disolve from shear sound waves.

To stop this from occuring, you must act swiflty and contact brian badonde.

The pill MUST be removed in the first 5 minutes, otherwise it may spread diseases into the eyeball such as testicular cancer, and sometimes in rare cases an acute strain of Down syndrome in the ear lobes.

Answer 3

Blinking, as opposed to batting, our eyes automatically supplies two forms of moisture to our eyes, to keep them from drying out, and to keep foreign matter from entering and irritating our eyes. Eyelids themselves, our built-in "wind-shield wipers," are merely folds of skin, controlled by muscles capable of expanding and contracting so rapidly, that blinking does not impair our vision. .

Blinking also protects the eye from dryness by irrigating, not by irritating, the eye, The eyelid, through suction, automatically draws the fluid we cry with from the well we refer to as the tear duct over the eyeball, to irrigate, and to moisturize the eye. The process is similar to the manner in which the farmer uses water to irrigate his crops during a dry spell.

Yet another benefit of blinking, is to shield the eye from foreign bodies. Our eyelashes, short, curved, hairs, attached to the eyelids, serve as dust-catchers, as the blinking reflex causes them automatically to lower, when exposed to harsh elements. Nature endowed the camel with extraordinarily long, curly, eyelashes, to protect his eyes from sudden sandstorms in the desert. Incidentally, the "camel eyelash" look is one many women attempt to duplicate by using an eyelash curler! Eyebrows, by the way, also serve their purpose, as they catch the run-off perspiration produces.

Answer 4

We blink about 15 times each minute, without thinking about it. The brain controls many actions such as this automatically. Blinking spreads taers across the eyes. This keeps the eyes clean and stops them from drying out. Tears keep the cornea at the front of the eye damp

Answer 5

People blink because our eyes require moisture. Blinking keeps the eyes from drying out and stops foreign material from entering our eyes. The eyelids act as "wind-shield wipers", and have 20-30 oil-producing glands. These coat the eyelids and eyelashes with the lubricant to prevent them from drying out.

Blinking also irrigates the eye, through suction, and draws the fluid we cry with from the well that is called the tear duct. This covers the eye and moisturises it.
