Are there different types of blepharitis?

Blepharitis is defined by its location on your lids.

Two types exist:

Anterior blepharitis: occurs when the eyelid’s front exterior, where eyelashes emerge, is red and swollen.

Posterior blepharitis: perhaps the more common type, happens when the oil (meibomian) glands in the moist underside of the eyelid produce oil erratically.
