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.
The doctor must give you your prescription for glasses at the end of your eye exam. The doctor must give you your contact lens prescription when your fitting is complete. A fitting may require more than one appointment. If the doctor is ready to sell you contacts, the fitting is complete.
