Be informed that your eyes are innately powerful since they have their defense mechanism to sustain good health. This system includes eyelashes, a tear film, and blinking. Wait, what? Blinking? How does this process help protect your eyes?
Understand that blinking presents several advantages for your eye function and health. On average, an adult person blinks about ten to twenty times in a minute. For how long does a blink last? A blink can go for about a tenth of a second.
The magic of a blink happens when your eyelids scatter fresh layers of eye water or tears throughout the surface of your eyes. Such a blink keeps your eyes hydrated and clears away micro-irritants such as dirt and dust. When you develop excess tears, they pass through your tear ducts to be drained out into your nasal passages. This case is the reason why your nose runs when you cry buckets.
Do you also observe that when you focus on something visually, you blink less? Yes, that is right – and it happens to all people. Do not worry because this is not an entirely bad thing. Avoid going on a day without blinking at the normal rate to prevent eye strain and dry eyes.
