An Optician is an eye care professional who provides corrective lenses based on a refraction prescription supplied by an optometrist or an ophthalmologist.
An Optometrist is a Doctor of Optometry, an O.D. (not to be confused with a Doctor of Medicine, an M.D.). To become an optometrist, one must complete pre-professional undergraduate college education followed by 4 years of professional education in a college of optometry. Some optometrists also do a residency.
An Ophthalmologist is an eye M.D., a medical doctor who is specialized in eye and vision care. Ophthalmologists are trained to provide the full spectrum of eye care, from prescribing glasses and contact lenses to complex and delicate eye surgery.
After 4 years of medical school and a year of internship, every ophthalmologist spends a minimum of 3 years of residency (hospital-based training) in ophthalmology. During residency, the eye M.D. receives special training in all aspects of eye care, including prevention, diagnosis, and medical and surgical treatment of eye conditions and diseases. An ophthalmologist may spend an additional year or two in training in a sub-specialty.
