The average person blinks 15 to 20 times a minute, which amounts to more than six million blinks a year.
When we blink all the way, by bringing the lids together during blinking, oil is better secreted from the Meibomian glands in the lids to lubricate the ocular surface.
In normal healthy people there is on average a five – fold decrease in blink rate during screen use.
It has been demonstrated that 10-20% of people show incomplete blinking whilst carrying out visual tasks.
Often when we are focused on computer screens, reading, driving, or the television, we tend to only blink half-way or incompletely without realization.
Blinking Sequence:
CLOSE-PAUSE-PAUSE-OPEN-RELAX
CLOSE-PAUSE-PAUSE-SQUEEZE-OPEN-RELAX
Note: To check your blink, place your finger gently on the bone to the outside corner of one eye. When you are blinking "normally", you should feel very little movement from the muscles around your eye.
The aggressive squeeze is used to ensure that the eyelid closure muscles are being utilized.
If you feel anything, you are using your defense muscles that run along the side of your head. Your blinking muscles are above your eyelids. The goal of these exercises are to get your blinking muscles working, this squeezing emphasizes complete closure and muscle contraction.
An efficient blink is full and complete meaning that the top lid lightly touches the bottom lid
Furthermore, an efficient blink is relaxed and light, meaning that the only the muscles of the eye are involved.
To make significant, improvement, practice this exercises every 30 minutes for at least 1 week.
It’s important to set up cues when doing focused work to ensure you are blinking all the way to better force oil out of the Meibomian glands and prevent tears from evaporating from the ocular surface.
