Definition: Dry eye syndrome is a common condition that occurs when the eyes do not produce enough tears or when the tears evaporate too quickly. This can result in dry, itchy, and irritated eyes.

Causes: The causes of dry eye syndrome can include aging, hormonal changes, certain medications, environmental factors (like wind or dry climates), and conditions that affect the ability to produce tears, such as autoimmune diseases or laser eye surgery.

Treatment: Treatment for dry eye syndrome aims to increase tear production, reduce tear evaporation, and improve tear quality. This can be achieved through the use of artificial tears, lubricating eye drops or ointments, prescription medications (such as anti-inflammatory eye drops or immunosuppressive drugs), and procedures like punctal plugs or tear duct surgery in severe cases. Lifestyle changes, like using a humidifier and taking regular breaks from screens, can also help manage symptoms.
