What is a common symptom of blepharitis?

Blepharitis is an inflammation of the eyelid margins, and a common symptom of this condition is redness and irritation. This occurs because the inflammatory processes affect the skin and the tissue surrounding the eyelids, leading to visible changes in color, swelling, and discomfort. Patients often report feelings of grittiness or burning sensations in conjunction with the redness, which indicates irritation caused by the inflamed tissues affecting the eyelid's normal function.

While other symptoms can accompany blepharitis, such as dry eyes or increased tears, the hallmark symptom that directly relates to the inflammation itself is the redness and irritation. Vision loss is not typically associated with blepharitis, as this condition primarily affects the eyelids rather than the inner structures of the eye responsible for vision. Understanding these symptoms is crucial for proper diagnosis and management of the condition.
