Eyelid inflammation, also known as blepharitis, is a condition characterized by redness, swelling, and irritation of the eyelids. It can occur due to various factors, including bacterial infections, allergies, or skin conditions like seborrheic dermatitis. Symptoms may include itching, crusting, and a gritty sensation in the eyes. Treatment for eyelid inflammation often involves maintaining good eyelid hygiene, such as warm compresses and gentle cleansing. In some cases, over-the-counter or prescription medications, like antibiotic ointments or anti-inflammatory drops, may be recommended to reduce symptoms and address underlying causes.
