Dry eye is a common condition that occurs when the eyes do not produce enough tears or when the tears evaporate too quickly, leading to insufficient lubrication on the eye's surface. This can cause discomfort, irritation, redness, a gritty or burning sensation, and even blurred vision. Factors contributing to dry eye include aging, hormonal changes, environmental conditions, prolonged screen time, certain medications, and underlying medical conditions like autoimmune disorders. Treatment for dry eye varies depending on the severity and underlying cause and may include artificial tears, prescription eye drops, lifestyle changes, or procedures such as punctal plugs to help conserve natural tears. Managing dry eye is important not only for comfort but also for preventing potential damage to the cornea and maintaining overall eye health.
