Why our eyes blink |
|
Answer» Eye blinks for the protection from damaging things like bright light, dust,etc. Blinking of eyes is needed to clear away dust particles and spread lubricating fluids across the eyeball. Every time you blink, your eyelids spread a cocktail of oils and mucous secretions across the surface of the eye to keep your globes from drying out. Blinking also keeps eyes safe from potentially damaging stimuli, such as bright lights and foreign bodies like dust. The very act of blinking suppresses activity in several areas of the brain responsible for detecting environmental changes, so that you experience the world as continuous. |
