- Nature of the Work
-
- Ophthalmic laboratory technicians also known as manufacturing
- opticians, optical mechanics, or optical goods workers make
- prescription eyeglass lenses. Some manufacture lenses for other
- optical instruments, such as telescopes and binoculars.
- Prescription lenses are curved in such a way that light is correctly
- focused onto the retina of the patient's eye, improving vision.
- Ophthalmic laboratory technicians cut, grind, edge, and finish
- lenses according to specifications provided by dispensing opticians,
- optometrists, or ophthalmologists, and then assemble the lenses with
- frames to produce finished glasses.
-
- 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
- also perform eye surgery. Dispensing opticians, who may also do
- work described here, help patients select frames and lenses, and
- adjust finished eyeglasses. (See the statement on physicians, which
- includes ophthalmologists, and the statements on optometrists and
- dispensing opticians elsewhere in the Handbook.)
-
- Ophthalmic laboratory technicians read prescription specifications,
- then select standard glass or plastic lens blanks and mark them to
- indicate where the curves specified on the prescription should be
- ground. They place the lens into the lens grinder, set the dials
- for the prescribed curvature, and start the machine. After a minute
- or so, the lens is ready to be finished by a process in which a
- machine rotates the lens against a fine abrasive to grind the lens
- and smooth out rough edges. The lens is then placed in a polishing
- machine, with an even finer abrasive, to polish the lens to a
- smooth, bright finish.
-
- Next, the technician examines the lens through a lensometer, an
- instrument similar in shape to a microscope, and makes sure the
- degree and placement of the curve is correct. The technician then
- cuts the lenses and bevels the edges to fit the frame, dips each
- lens into dye if the prescription calls for tinted or coated lenses,
- polishes the edges, and assembles the lenses and frame parts into a
- finished pair of glasses.
-
- In small laboratories, technicians generally handle every phase of
- the operation. In large ones, technicians may specialize in one or
- more steps, assembly-line style.
-
- Nearly all ophthalmic laboratory technicians learn their skills on
- the job.
-
- Working Conditions
-
- Ophthalmic laboratory technicians work in relatively clean and
- well-lighted laboratories and have limited contact with the public.
- Surroundings are relatively quiet despite the humming of machines.
- At times, technicians may need to wear goggles to protect their
- eyes, and may spend a great deal of time standing.
-
- Most ophthalmic laboratory technicians work a 5-day, 40-hour week,
- which may include weekends, evenings, or occasionally, some
- overtime. Some work part time.
-
- Ophthalmic laboratory technicians need to take precautions against
- the hazards associated with cutting glass, handling chemicals, and
- working near machinery.
-
- Employment
-
- Ophthalmic laboratory technicians held about 19,000 jobs in 1992.
- About half of these jobs were in retail stores that manufacture and
- sell prescription glasses mostly chains of optical goods stores or
- independent retailers. Most of the rest were in optical
- laboratories. These laboratories manufacture eyewear for dispensing
- by retail stores that sell but do not fabricate prescription
- glasses, and by ophthalmologists and optometrists. A few work for
- optometrists or ophthalmologists who dispense glasses directly to
- patients.
-
- Training, Other Qualifications, and Advancement
-
- Nearly all ophthalmic laboratory technicians learn their skills on
- the job. Employers filling trainee jobs prefer applicants who are
- high school graduates. Courses in science and mathematics are
- valuable; manual dexterity and the ability to do precision work is
- essential.
-
- Technician trainees start on simple tasks such as marking or
- blocking lenses for grinding, then progress to lens grinding, lens
- cutting, edging, beveling, and eyeglass assembly. Depending on the
- individual's aptitude, it may take 6 to 18 months to become
- proficient in all phases of the work.
-
- Some ophthalmic technicians learn their trade in the Armed Forces.
- Others attend the few programs in optical technology offered by
- vocational-technical institutes or trade schools. These programs
- have classes in optical theory, surfacing and lens finishing, and
- the reading and applying of prescriptions. Programs vary in length
- from 6 months to 1 year, and award certificates or diplomas.
-
- Ophthalmic laboratory technicians can become supervisors and
- managers. Some technicians become dispensing opticians, although
- further education or training may be required.
-
- Job Outlook
-
- Employment of ophthalmic laboratory technicians is expected to
- increase about as fast as the average for all occupations through
- the year 2005 due to rising demand for corrective lenses.
- Nonetheless, most job openings will come from the need to replace
- technicians who transfer to other occupations or leave the labor
- force.
-
- Demographic trends make it likely that many more Americans will wear
- glasses in the years ahead. Not only will the population grow, but
- the number of middle-aged and older adults will grow particularly
- rapidly. Middle age is a time when many people use corrective
- lenses for the first time, and older persons require appreciably
- more vision care than the rest of the population.
-
- The public's heightened awareness of vision care should also
- increase demand for corrective lenses. The emergence of eyewear as
- a fashion item eyewear now comes in an assortment of attractive
- shapes and colors has been enticing many people to purchase two or
- three pair of glasses rather than just one. Most new jobs for
- ophthalmic laboratory technicians will be in retail optical chains
- that manufacture prescription glasses on the premises and provide
- fast service.
-
- Earnings
-
- According to the Opticians Association of America, the beginning
- average salary for ophthalmic laboratory technicians in retail
- optical stores was $15,040 in 1992. Those with 3 to 5 years of
- experience averaged $16,700; 6 to 9 years, $21,700; and 10 years or
- more, $24,370. Trainees may start at the minimum wage.

- Workers in other precision production occupations include biomedical
- equipment technicians, dental laboratory technicians, orthodontic
- technicians, orthotics technicians, prosthetics technicians, and
- instrument repairers.
