Eye irritation and pain may be caused by dryness, allergy, infection, eye strain, dust exposure, or improper use of contact lenses. Since different eye conditions require different treatment, it is important not to use antibiotic or steroid eye drops without medical advice. You can try resting the eyes, limiting screen time, washing the eyes gently with clean water, and using lubricating artificial tear drops if the irritation is mild. However, if you develop redness, swelling, blurred vision, discharge, severe pain, or sensitivity to light, consult an eye doctor promptly because infections or corneal injuries may need urgent treatment. Early examination helps prevent complications and protects vision.
