opticianry

Opticianry is the profession concerned with the preparation, fitting, and verification of eyeglasses and related eyewear according to an eye prescription. Opticians work from prescriptions issued by optometrists or ophthalmologists to select appropriate lenses, frame styles, and coatings, and they may also fit and dispense contact lenses in some settings. The field is distinct from optometry, which performs eye examinations and diagnoses, and from ophthalmology, which treats eye diseases and performs surgery.

Core duties include interpreting prescriptions, choosing lens materials and designs (including single-vision, bifocal, and progressive lenses), and determining fitting parameters such as pupillary distance and frame size. Technicians measure, cut, and finish lenses, mount them into frames, and adjust or repair eyewear to ensure proper alignment and comfort. Some opticians perform basic eye health screenings or vision tests, but they do not replace comprehensive eye exams.

Education and licensure vary by jurisdiction. Many regions require formal training through an accredited program or apprenticeship, followed by certification or licensing. US professionals may earn certification from the American Board of Opticianry (ABO) and the National Contact Lens Examiners (NCLE). In the UK, registration with the General Optical Council and related diplomas are common. Continuing education is often required to maintain credentials.

Work settings include retail optical chains, independent eyewear shops, hospital or clinic dispensaries, and optical laboratories. Opticians may work directly with customers, or in lab roles focused on lens fabrication and edging, coating applications, and quality control.

Historically, the craft emerged with the invention of eyeglasses in the late Middle Ages and evolved through the industrial and optical revolutions to support mass production of lenses and frames. Today, opticianry combines technical optical knowledge with customer service and retail skills.
