Eye Blinking Blog

Blinking is a reflex and we all do it without even realizing it. But did you know that blinking is essential to our eye health? In this blog, we will explore the importance of eye blinking and how sometimes we blink more often than required.

What is the reason for eye blinking?

Blinking is a natural reflex that helps to lubricate and protect our eyes. Every time we blink, our eyelids spread a layer of tear film over the surface of our eyes. This tear film contains vital nutrients and antibodies that keep our eyes healthy and moist.

Benefits of Blinking

  1. Keeps eyes moist
  2. Flushes out foreign particles
  3. Protects the eyes
  4. Reduces eye strain and fatigue

How often do we need to blink?

The number of times you blink changes with age. Newborns only blink about two times a minute. That number goes up as they grow. Teens blink around 15 times a minute. It’s about the same in adults.

However, sometimes some may blink very frequently much more than normal

Lots of things can lead to excessive blinking. In order of how common these causes are:

  • Dry eye

Excessive Eye Blinking Diagnosis
