Eye health is a broad field of study that focuses on the prevention, diagnosis, and treatment of conditions that affect the eyes and vision. This includes diseases such as glaucoma, cataracts, and macular degeneration, as well as refractive errors like nearsightedness and farsightedness. Research in this area also explores the impact of lifestyle factors, genetics, and environmental influences on eye health, and seeks to develop new technologies and treatments to improve vision and prevent vision loss. Eye health research is essential for maintaining good vision and overall quality of life for individuals of all ages.
