The human tear layer has three main layers. The mucin layer is closest to the eye. The aqueous or water layer is in the middle and the lipid or oil layer is the outermost.
The pumping action occurs during a blink because a muscle named the Riolan muscle surrounds the meibomian glands and is only activated when the eyelids come together during a blink. A partial blink or an incomplete blink will not activate the Riolan muscle.
Eyelid Exercises do two things: 1. They make up for missed blinks and 2. They strengthen the Riolan muscle and make our blinks more productive to release more oil from the meibomian glands.
How to do Eyelid Exercises
Close your eyes gently and hold your fingers at the corners of your eyes and purse your eyes together to blink. Your blinking muscles are above the eyelids. If you feel any movement under your fingers, you are using the wrong muscle group. Hold the blink for 3 seconds and release. Repeat 10 times. Try to repeat several times throughout.
