Optometry is a healthcare profession that deals with the examination, diagnosis, and treatment of various visual disorders and problems related to the eyes. Optometrists are the healthcare professionals who specialize in this field and provide services such as vision testing, prescribing corrective lenses or eyeglasses, diagnosing and treating eye diseases and disorders, providing low vision aids, and counseling patients on maintaining good eye health. In addition to diagnosing and treating vision problems, optometrists also play an important role in preventing eye diseases and promoting eye health through regular eye exams, education about proper eye care and safety, and recommending lifestyle changes to reduce the risk of developing eye diseases. Optometry requires a strong foundation in science, mathematics, and biology, and requires a degree in optometry from an accredited school or college of optometry. Optometrists must also be licensed by their state or province to practice optometry. In some countries, optometrists may also be allowed to perform certain surgical procedures related to the eyes, such as laser eye surgery.
