We know that eye doctors are different from normal doctors.

What kinds do they have what are they called and what do they do? Let Doglasses tell you.
Ophthalmologists :
Ophthalmologists are licensed physicians and surgeons. They have an extensive level of education – typically twelve to fifteen years of undergraduate work, medical school or advanced training. They can perform ophthalmologic examinations, prescribe vision correction (eyeglasses or contact lenses), medications, diagnose and treat diseases or disorders of the eye. In addition, ophthalmologists can diagnose general diseases of the body and treat ocular manifestations of systemic diseases.
Optometrists :
Optometrists are licensed healthcare providers who have completed four years of optometry study and four years of undergraduate work. They can perform eye exams, prescribe and dispense eyeglasses or contact lenses, and diagnose vision disorders and eye disease. Optometrists can prescribe medications to treat certain eye diseases.
Opticians :
Opticians are technicians who have graduated from a two-year program at a community or technical college. They are qualified to make, fit, and dispense eyeglasses and contact lenses, either in an optical laboratory or for retail sale to the public. Opticians do not perform patient examinations or write prescriptions for eye correction or medication.

They are different doctors and have different techniques. Don’t confuse them.
