dry eyes (keratoconjunctivitis sicca)

Dry eyes, or keratoconjunctivitis sicca, occur when the eyes don't produce enough tears or the tears evaporate too quickly. Tears are essential for keeping the eyes moist, nourishing the surface, and protecting against irritation and infection. Without adequate lubrication, you might experience discomfort, a gritty feeling, redness, blurred vision, or sensitivity to light. Dry eyes can result from aging, certain medications, environmental factors, or underlying health conditions. Proper diagnosis and treatment help restore moisture, relieve symptoms, and protect eye health.
