Your symptoms suggest blepharitis (eyelid inflammation), which is commonly associated with dry eye syndrome. For immediate relief, use preservative-free lubricating eye drops (artificial tears) 4 to 6 times a day, especially during screen use. Apply a warm compress to your closed eyelids for 5 to 10 minutes twice daily, followed by gently cleaning your eyelid margins with over-the-counter eyelid wipes to clear the crusty discharge. Please consult an eye specialist for an evaluation. They may prescribe antibiotic eye drops or ointment (such as erythromycin) if a bacterial infection is present. Avoid wearing contact lenses or eye makeup until symptoms resolve.
