Optometry is a branch of healthcare that focuses on the eye and visual system. Optometrists are healthcare professionals who provide primary eye care services, including vision testing, eye exams, prescribing eyeglasses and contact lenses, diagnosing and treating eye diseases, and managing conditions such as glaucoma and macular degeneration. They play a crucial role in helping individuals maintain good eye health and achieve optimal vision. Optometry research often focuses on understanding the mechanisms of vision and eye diseases, improving diagnostic tools and treatment options, and exploring new technologies for vision correction.
