What causes ocular rosacea?

ANSWER

Scientists don’t know exactly why it happens, but researchers have found that 85% of people with ocular rosacea have blocked oil glands around the edges of their eyelids. These glands prevent dryness. If they are blocked, the area around them can swell and get irritated. This can lead to redness and itching in your eyes and crust in your eyelashes. Some scientists believe mites -- tiny spider-like creatures that live in hair follicles on your face and lashes -- can block the glands.
