Can having a slower/reduced blink rate cause meibomian gland dysfunction?

There is no evidence to suggest that blink rate worsens meibomian gland function. However, as mentioned previously, a diminished blink rate, or blink excursion can hamper proper spreading of the tear film layer across the surface of the eye and lead to dry eye symptoms. This is analogous to having windshield wipers that travel only halfway along the windshield.

A slower blink rate could reduce dispersion of lipid materials and give the appearance of MGD. People who suffer from MGD will often increase or prolong blinks to help with the issue.
