Winter eye care: Prevent infections and protect your eyes

Winter's dry air, heaters, and seasonal allergies increase eye infections like viral and allergic conjunctivitis, blepharitis, and dacryocystitis. Symptoms include redness, itching, watery or sticky eyes, and blurred vision. Prevention includes lubricating drops, hydration, screen breaks, sunglasses, hygiene, humidifiers, and reduced contact lens use to keep eyes healthy and protected.
