The Science Behind: Blinking

Cover page- Khushi Bhatia

Fun fact: An average person blinks 15-20 times per minute which is about 28,000 times in a day.

Woah! That's a big number! But wait... Why do we blink?

Blinking cleans and moisturizes the eye. It helps us focus and keep attention, and it is like a tiny mental break. So when we open our eyes again, it helps us pay more attention. Blinking helps spread water, oil, and mucus (a slippery, sticky substance) across our eyes and wipes out the dust.

Experts have found out that blinking is not completely random. While reading, humans tend to blink at the end of sentences or pages. While listening to music, we tend to blink when the song takes pauses.

Blinking is a type of reflex. It is something we don't think about doing; it happens automatically. Sneezing, breathing, and coughing are all examples of reflexes.

Fun fact #2: Snakes don't blink because they do not have eyelids.

Here's a riddle for you:

Question: I stare at you, you stare at me. I have 3 eyes, yet can't see. Every time I blink, I give you commands. You do as you're told with your feet and hands. What am I?

Answer: Traffic Light

That's all for today! See you next time!
