Ophthalmic laboratory
technicians—also known as manufacturing opticians,
optical mechanics, or optical goods workers—make
prescription eyeglass or contact lenses. Prescription
lenses are curved in such a way that light is correctly
focused onto the retina of the patient’s eye,
improving his or her vision. Some ophthalmic laboratory
technicians manufacture lenses for other optical instruments,
such as telescopes and binoculars. Ophthalmic laboratory
technicians cut, grind, edge, and finish lenses according
to specifications provided by dispensing opticians,
optometrists, or ophthalmologists and may insert lenses
into frames to produce finished glasses. Although
some lenses still are produced by hand, technicians
are increasingly using automated equipment to make
lenses.
Ophthalmic
laboratory technicians should not be confused with
workers in other vision care occupations. Ophthalmologists
and optometrists are “eye doctors” who examine
eyes, diagnose and treat vision problems, and prescribe
corrective lenses. Ophthalmologists are physicians
who perform eye surgery. Dispensing opticians, who
also may do the work of ophthalmic laboratory technicians,
help patients select frames and lenses, and adjust
finished eyeglasses. (See the statement on physicians
and surgeons, which includes ophthalmologists, as
well as the statements on optometrists and opticians,
dispensing, elsewhere in the Handbook.)
