Concept
Optician
Summary
An optician is an individual who fits eyeglasses or contact lenses by filling a refractive prescription from an optometrist or ophthalmologist. They are able to translate and adapt ophthalmic prescriptions, dispense products, and work with accessories. There are several specialties within the field.
A dispensing optician is anyone who prepares, fits, and dispenses prescription lenses, spectacles, eyeglasses, contact lenses, or any other type of vision-correcting optical device to the intended user. They may interpret optical prescriptions issued by an ophthalmologist, optometrist, or physician for the lab optician who fabricates vision-correcting optical lenses. They also measure inter-ocular or pupillary distances, vertex distances, pupil fitting heights, and frame angles to determine the proper position of vision-correcting lenses. In addition, they adapt, modify or align frames with vision-correcting lenses to the face of the intended wearer, Dispensing opticians must have a basic knowledge of laboratory techniques such as lens surfacing and lens preparation.
Ophthalmic laboratory technicians must understand optics and how to use machinery in order to surface, coat, edge, or finish lenses according to specifications provided by dispensing opticians. They typically insert lenses into frames, also called glazing, to produce finished glasses and conduct all quality and safety testing required by the respective local and country regulations. Although most lenses are designed with fully automated equipment, such as computer-based generators, automatic edgers, and lens measurement instruments, a highly-skilled lab optician will often finish lenses by hand for more difficult prescriptions and lens designs in order to have the best-finished outcome.
Contact Lens Fitters may work independently or under the direction of an ophthalmologist or optometrist to fill a doctor's prescription for contact lenses. A patient must obtain a prescription for contact lenses from a physician and then the fitter will review contact lens handling, fitting, and follow-up care.
