Dry eyes

Short summary: Dry eye develops when tears are insufficient in quantity or poor in quality. It can cause burning, stinging, foreign-body sensation, fluctuating vision, and light sensitivity.

Basic information about dry eye

People with dry eye may feel burning, scratchiness, eye fatigue, redness, blurred vision, or paradoxical watering. Excess tearing can happen because irritated eyes reflexively produce watery tears that do not solve the underlying problem. ^[1][2]

Dry eye may be related to screen use, aging, environmental exposure, meibomian gland dysfunction, contact lenses, autoimmune disease, medications, or eyelid problems. Diagnosis may involve symptom review and an eye examination. Treatment can include artificial tears, environmental adjustments, eyelid care, and more targeted treatment depending on the cause. ^[1][2][3]

Short conclusion: Dry eye is common but not always minor. Severe pain, marked vision change, or one-sided red painful eye require urgent evaluation. ^[1][2]
