Optometry is a healthcare profession that involves the examination, diagnosis, treatment, and management of disorders and diseases related to the visual system, eye, and associated structures. Optometrists are healthcare professionals who specialize in providing primary eye care, including eye exams, vision testing, prescription of corrective lenses, and the diagnosis and treatment of eye conditions. Optometrists also play a crucial role in the early detection and management of eye diseases such as glaucoma, cataracts, and macular degeneration. They may work in private practices, hospitals, clinics, or other healthcare settings. In addition to prescribing corrective lenses, optometrists may also provide vision therapy, which involves exercises and activities to improve the function of the visual system. They may also provide advice on eye care, including strategies for preventing eye injuries, maintaining healthy vision, and managing chronic eye conditions. To become an optometrist, an individual must complete a Doctor of Optometry (OD) degree from an accredited optometry school and pass a licensing exam. The specific requirements for licensure may vary depending on the country or state in which the optometrist practices.
