What characterizes blepharitis?

Blepharitis is characterized by redness and swelling of the eyelids. This condition occurs due to inflammation of the eyelid margins, often causing discomfort, itching, and irritation. The inflammation typically results from several factors, including bacteria, skin conditions, or clogged oil glands.

While dryness and loss of eyelashes, excessive tearing, and blurred vision can occur with various eye conditions, they are not definitive characteristics of blepharitis itself. Blepharitis primarily manifests through the swelling and redness of the eyelids, which is a direct result of the inflammatory processes affecting the eyelid margins. Recognizing these specific symptoms is crucial for effective diagnosis and subsequent treatment of the condition.
