“Optometry is the field involving virtually everything that has to do with eyes and vision, including examination, diagnosis and treatment of the eyes and surrounding structures, and the treatment of vision problems.
Doctors of Optometry (ODs) are independent primary health care professionals for the eyes. They should not be confused with ophthalmologists or dispensing opticians. Ophthalmologists are physicians who perform eye surgery, in addition to diagnosing and treating eye conditions. Dispensing opticians fit eyeglasses and contact lenses, following prescriptions written by ophthalmologists or optometrists.”
