How you prepare
There are three types of eye specialists. Which specialist you choose might be a matter of preference or will depend on the nature of your eye problem.
Ophthalmologists. These medical doctors provide full eye care, such as performing complete eye exams, prescribing corrective lenses, diagnosing and treating complex eye diseases, and performing eye surgery.
Optometrists. These doctors provide many of the same services as ophthalmologists, such as performing complete eye exams, evaluating your vision, prescribing corrective lenses, diagnosing common eye disorders and treating selected eye diseases with drugs. If you have a complex eye problem or need surgery, your optometrist can refer you to an ophthalmologist.
Opticians. They fill prescriptions for eyeglasses, including assembling, fitting and selling them. Some opticians also sell contact lenses. Opticians do not provide eye health evaluations.
