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.
They may require you to pay for the eye exam, fitting, and evaluation before giving you a copy of the contact lens prescription, but only if the prescriber also requires immediate payment from patients whose eye exams reveal no need for glasses, contact lenses, or other corrective eye care products.
