A detailed examination of the eye can reveal conditions such as high blood pressure or diabetes. Optometrists make a health assessment, offer clinical advice and when necessary prescribe spectacles or contact lenses. In addition, optometrists can dispense, fit and supply spectacles or contact lenses. They also supervise trainee optometrists and dispensing opticians, and medical students.
Many people only think of their optometrist as the doctor to see when they need glasses or contact lenses. Optometrists do much more. Doctors of optometry treat and manage eye diseases. As doctors, they regularly diagnose diseases both of the eye and the body. Many systemic diseases like diabetes or high blood pressure are first found by optometrists during a comprehensive eye exam.
