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.
An optometrist is a doctor of optometry (OD) who is trained in the study of vision. The optometrist performs routine eye care, conducts eye examinations and prescribes corrective lenses. Optometrists also diagnose and prescribe treatment for eye diseases. Treatment may include medication in the form of drops, pills or injections.
