how fast do you blink

You blink surprisingly fast: a typical blink lasts about 0.1 seconds (100 milliseconds), and most people blink around 15–20 times per minute.
Quick Scoop: How fast do you blink?
Basic numbers
- Duration of one blink: about 0.1 seconds on average, sometimes up to 0.4 seconds.
- Blinks per minute: roughly 15–20 under normal, relaxed conditions.
- Blinks per day: on the order of 15,000–20,000 times, assuming a typical waking day.
If you think of a wall clock, you could blink about three times during a single one‑second tick.
How fast are the eyelids actually moving?
High‑speed camera studies show that the eyelid can reach peak speeds of over 200 millimetres per second when closing, with somewhat slower speeds when opening again.
The whole motion is so quick and smooth that your brain largely edits it out of your conscious experience.
Why you blink that fast and that often
- Blinks spread tears and oils over the cornea to keep it clean, smooth, and moist.
- They help clear tiny dust particles and protect the eye from irritants and bright light.
- There is evidence that blinking also gives the brain tiny “micro‑breaks” to reset attention and process information.
An everyday example: when you stare at a screen or read intently, your blink rate often drops, which is why your eyes feel dry after a long session.
TL;DR: You blink about 15–20 times a minute, each blink taking roughly a tenth of a second, with your eyelids briefly moving at over 200 mm/s to keep your eyes protected and lubricated.
