What is a common effect of blepharitis on tear production?

Blepharitis, an inflammation of the eyelids, commonly leads to frequent dry eye symptoms. This condition can disrupt the normal functioning of the meibomian glands, which are responsible for producing the oily layer of the tear film. When the meibomian glands are not functioning properly, the tears may evaporate more quickly, resulting in dry and uncomfortable eyes.

Additionally, blepharitis may alter the balance of the tear film, exacerbating sensations of dryness. The eyelids may also become crusted or irritated, contributing to the discomfort associated with dry eye symptoms. Due to these factors, individuals with blepharitis often experience a feeling of dryness in their eyes, making it a common and notable effect on tear production.
