Swelling of the eyelids due to Meibomian gland dysfunction is usually caused by blockage of oil glands, leading to irritation, heaviness, or lump-like swelling, and it can persist if not managed regularly. The main treatment is simple home care: apply warm compresses to the closed eyelids for 10-15 minutes, 2-3 times daily, followed by gentle lid massage and cleaning (lid hygiene) to help open the blocked glands. Using lubricating eye drops can reduce discomfort. Avoid rubbing the eyes and reduce screen strain. If symptoms continue for weeks (as in your case), an eye specialist may prescribe antibiotic or anti-inflammatory eye drops/ointments or perform procedures to clear the blockage. Seek care sooner if there is severe pain, vision changes, or increasing redness.
