Blepharitis. Blepharitis means inflammation of the eyelid margins. It is easily diagnosed with a magnifying slit lamp by an eye doctor. If you've every had a stye (chalazion) in your lid, you most likely do have blepharitis. Lids getting stuck together with discharge can be a sign of blepharitis, but can also be associated with other eye conditions causing discharge (examples: dry eyes, eye allergies).
