Meibomian Gland Dysfunction (MGD): The Cause Of Your Dry Eyes? by All About Vision
Meibomian gland dysfunction is blockage or some other abnormality of the meibomian glands so they don't secrete enough oil into the tears. Because the tears then evaporate too quickly, MGD is a leading cause of dry eye syndrome. It also is associated with an eyelid problem called blepharitis.

Research in the past decade has shown that the kinds of light our devices give off-high-energy, short-wavelength blue and violet light—may affect and even age the eyes.

Although the research on this topic is in early stages, there are signs that overexposure to blue light—and the obsessive way many of us stare at our screens—could contribute to serious conditions such as age-related macular degeneration (AMD), which can lead to blindness.
