optician, filler of prescriptions for and dispenser of corrective lenses. An optician may grind lenses as instructed by the prescription of an optometrist (see optometry) or ophthalmologist (see ophthalmology) or transcribe the instructions for laboratory mechanics. The optician also fits and adjusts the lenses to the client and makes suggestions as to the selection of frames. Increasingly, opticians have taken over the task of fitting contact lenses as well as eyeglasses. Some states require that lab technicians and retail merchandisers be licensed opticians. Requirements may be met through academic training or through a laboratory apprenticeship.
