An optician is a person who reads prescriptions for visual correction, orders lenses, and dispenses eyeglasses and contact lenses. The term is most often used to refer to the profession of providing eyeglass lenses from refraction prescriptions supplied by an ophthalmologist or optometrist. Many people confuse the roles of these three types of eye care practitioners. Ophthalmology is the branch of medicine which deals with the diseases of the eye and their treatment; Optometry is the health care profession concerned with examination, diagnosis, and treatment of the eyes and related structures, and with determination and correction of vision problems using lenses and other optical aids. The Optician is the practitioner who will fill the prescriptions written by the other two types of eye care practitioners.
