Dry eye is a common condition characterized by a lack of lubrication and moisture on the surface of the eye, leading to discomfort, irritation, and potential damage to the cornea. Research in this area focuses on understanding the underlying causes of dry eye, developing effective treatments, and improving the overall quality of life for individuals with this condition. This research may involve studying the role of tear production and composition, examining environmental and lifestyle factors that contribute to dry eye, and testing new therapeutic approaches such as artificial tears, medications, and eye drops. Ultimately, the goal of research in dry eye is to better diagnose, manage, and prevent this condition to improve the vision and comfort of those affected.
