Understanding Sore Eyes: Causes, Symptoms, and Treatment

Common causes, roughly by frequency: digital eye strain (8+ hours screen daily; dry burning eyes, blurred vision after long work, headache, neck pain — usually both eyes, worse by evening); dry eye disease (chronic; worse in AC environments, polluted cities, contact lens wearers, women during menopause; burning, gritty foreign-body feeling, paradoxical reflex watering); viral conjunctivitis / eye flu (sudden onset, discharge, contagious, spikes in monsoon); allergic conjunctivitis (itching dominant, seasonal, family history of atopy); blepharitis (chronic eyelid inflammation with crusty lashes, morning discomfort); bacterial conjunctivitis (thick pus discharge); contact lens overwear or infection; foreign body (grit, dust, insect — needs removal); corneal abrasion (usually after minor injury; painful); uveitis or iritis (sight-threatening; deep aching pain + light sensitivity + vision reduction — needs urgent ophthalmologist); and angle closure glaucoma (severe eye and head pain + nausea + halos around lights + acute vision loss — MEDICAL EMERGENCY). Sore eyes lasting more than 3 days warrant ophthalmologist evaluation.

Evidence-based home care: cool compress (clean cloth soaked in cool water, applied 10-15 min 3-4x daily) reduces swelling and gives comfort; warm compress (5-10 min once daily) helps blepharitis and meibomian gland dysfunction by melting blocked oil glands; preservative-free artificial tears 4-6 times daily are safe for long-term use; rest from screens with the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds), and take proper lunch breaks; blink consciously — computer users blink about 60% less than normal; adequate room lighting reduces screen glare; screen at arm's length, slightly below eye level; avoid direct AC or heater airflow on your face; a humidifier helps in AC rooms; adequate hydration (2-3 litres water daily); omega-3 supplementation (1000-2000 mg EPA/DHA daily) helps some people with chronic dry eye — evidence is modest. AVOID: kajal, kohl, or eye makeup when eyes are irritated; rubbing your eyes; old contact lenses or expired drops; sharing eye drops; rose water drops (unregulated, contamination risk); homeopathic 'eye drops' (no evidence); colloidal silver drops (harmful); steroid drops without prescription (worsen infections, cause glaucoma and cataract); and antibiotic drops for every red eye (usually unnecessary and promotes resistance). See a doctor for symptoms lasting more than 3 days or any red-flag features.

Same-day emergency ophthalmology needed for: sudden severe eye pain with vision loss, halos around lights, and nausea/vomiting — acute angle closure glaucoma can permanently damage vision within hours; chemical splash (acid, alkali, detergent) — immediate copious water irrigation for 15-30 minutes THEN emergency care, because delay causes permanent damage; penetrating eye injury from sharp objects, metal fragments, or glass — do NOT remove the foreign body, cover with a shield, go to emergency; sudden vision loss without pain (could be retinal detachment, vascular occlusion, or optic neuritis); sudden onset of flashes of light + floaters + vision loss (retinal tear/detachment); photophobia + deep aching eye pain + vision reduction (anterior uveitis/iritis); contact lens wearer with a red painful eye (high risk of microbial keratitis); a visible white spot on the cornea (corneal ulcer); post-surgical eye with sudden pain or vision change; and one-sided severe symptoms with facial swelling and fever (orbital cellulitis is a medical emergency). Go to a hospital eye emergency department with 24/7 ophthalmology — don't wait for an OPD appointment, and don't self-treat serious eye emergencies. Vision loss can be permanent within hours.
