An optical lab technician makes prescription eyeglasses and contact lenses.
The Bureau of Labor Statistics calls the occupation ophthalmic laboratory technician, lists it under SOC code 51-9083, and notes it is also known as optical laboratory technician — a different job from a dispensing optician.
BLS says the work is typically done with automated equipment.
O*NET's task list includes selecting lens blanks, molds, tools and polishing or grinding wheels to production specs, setting up cutting, grinding, polishing or coating machines, and mounting lens blanks in the machine chucks.
BLS describes production phases that can include polishing, measuring and testing.
What is an optical lab technician?
Ophthalmic laboratory technicians make prescription eyeglasses and contact lenses, and BLS notes they are also commonly known as optical laboratory technicians.
The work is production work rather than client-facing work.
BLS says the occupation should not be confused with dispensing opticians, and O*NET's top-rated task for dispensing opticians is client-side measuring: bridge and eye size, temple length, vertex distance, pupillary distance and optical centers.
The occupation's definition covers contact lenses as well as eyeglasses.
O*NET's sample job titles for the occupation include Surfacing Technician, Edger Technician, Finishing Lab Technician, Lens Grinder and Polisher, and Line Operator — sample titles for the single occupation 51-9083.
BLS's OEWS counted 18,660 wage-and-salary jobs nationally in May 2025, with a median annual wage of $39,460.
That is a count of payroll jobs, and 51-9083 is its own line in the wage tables — separate from the dispensing optician occupation.
Surfacing vs finishing: the two halves of the lab
The occupation's title list clusters around two halves of production.
BLS names surfacing and finishing as skill areas that some schools teach, and O*NET's title list tracks the split: Surfacing Technician on one side, Edger Technician and Finishing Lab Technician on the other, alongside Lens Grinder and Polisher and Line Operator.
Surfacing is the machine work on the lens blank.
O*NET's surfacing tasks for ophthalmic lab technicians include mounting lens blanks in the chucks of cutting, polishing, grinding or coating machines, setting those machines up, and selecting lens blanks, molds, tools and polishing or grinding wheels to production specifications.
Surfacing is also precision setup: positioning cutting tools to the specified curvature and depth of cut is one of the tasks O*NET lists.
Finishing is the other half of the title list.
The Edger Technician and Finishing Lab Technician titles belong to it.
BLS describes the one-phase division separately: in the large facilities it describes, a technician may be responsible for only one phase of production, such as polishing, measuring or testing.
BLS draws the staffing pattern by employer size: in small offices and retail establishments, technicians may handle every phase of production, while large manufacturing and wholesale facilities divide the work into single phases.
The two halves are also a real skill boundary.
South Carolina says the lens-processing skill tested for optician licensure does not include the surface grinding done by workers in wholesale laboratories — wholesale surfacing sits outside the dispensing skill set the state tests.
Daily duties and quality control
A lab technician's day runs from prescription to finished lens.
The through-line is machine work to specification: select the right blanks and tooling, set up the cutting, grinding, polishing or coating equipment, and mount blanks in the machine chucks, all to the production specs O*NET describes for the occupation.
Phases such as polishing, measuring and testing are how BLS describes the division of labor inside large labs.
In small offices and retail establishments, BLS says technicians may handle every phase of production themselves.
Quality control has a federal anchor.
FDA rule 21 CFR 801.410 requires eyeglasses and sunglasses to have impact-resistant lenses, unless the doctor directs otherwise in writing.
The FDA's test is physical: a 5/8-inch steel ball weighing about 0.56 ounce is dropped from 50 inches onto the lens, which must not fracture.
The rule also distinguishes materials.
Each finished impact-resistant glass lens must be tested individually, while plastic lenses may be batch tested by the manufacturer.
Where lab techs work: wholesale, chain, in-office labs
BLS's broad map is size-based: in small offices and retail establishments, technicians may handle every phase of production, while in large manufacturing and wholesale facilities they may be responsible for only one phase.
BLS's OEWS industry rows for May 2025 show four of the industries where the occupation's wage-and-salary jobs sit.
| Industry | Jobs (May 2025) |
|---|---|
| Medical equipment and supplies manufacturing | 6,310 |
| Health and personal care retailers | 4,500 |
| Offices of optometrists | 2,580 |
| Offices of physicians | 1,750 |
The table is not a complete list of industries; the occupation had 18,660 wage-and-salary jobs nationally in May 2025.
Chains run labs at both ends of the size range.
National Vision's fiscal 2025 annual report describes Eyeglass World stores with on-site labs that can process certain orders with same-day service.
America's Best orders go through centralized labs in Lawrenceville, Georgia; St. Cloud, Minnesota; Plano, Texas; and Salt Lake City, Utah, plus an outsourced lab in Mexico.
As of December 31, 2025, Warby Parker reported 323 retail stores and two in-house optical labs, in Sloatsburg, New York, and Las Vegas, Nevada.
Most of its glasses are processed at labs — including a contracted lab in China — rather than in stores.
At the wholesale end, scale gets large: EssilorLuxottica's corporate homepage cited 602 production facilities and laboratories worldwide when read in October 2026.
That is a global figure for the company, not a US lab count.
Offices of optometrists employed 2,580 lab technicians in the May 2025 count — the in-office lab.
That setting is the one closest to BLS's small-office picture, where technicians may handle every phase of production.
Skills and physical demands
The core skills are machine and specification skills: setting up equipment, selecting tooling to production specs, and positioning cutting tools to a specified curvature and depth of cut.
The work is physical.
BLS says lab technicians may spend much of the day standing or bending, and that they wear goggles, gloves or masks.
Protective eyewear is not just habit — it is regulated: OSHA's 29 CFR 1910.133 requires workplace protective eyewear to comply with ANSI/ISEA Z87.1, naming the 2010, 2003 or 1989 (R-1998) editions of the standard.
Schedules skew full time: BLS says most lab technicians work full time, and schedules may vary.
Our research found no BLS shift-pattern breakdown for the occupation, so treat any shift pattern a job ad implies as employer-specific rather than an industry norm.
How to become an optical lab technician
The entry route BLS describes is short: lab technicians typically need a high school diploma and moderate-term on-the-job training.
Certification is optional, though employers may prefer a certificate or an associate degree, and some schools teach surfacing and finishing directly.
BLS's Employment Projections list a high school diploma or equivalent as the occupation's typical entry education.
State law can still reach production work, so the route is not identical everywhere.
Connecticut requires a Department of Public Health license to produce or reproduce ophthalmic lenses, mount them, or fit them, so in Connecticut optical lab work as well as fitting is licensed work.
South Carolina, by contrast, excludes the surface grinding done in wholesale laboratories from the lens-processing skill its optician licensure exam tests.
State boards decide where production becomes licensed work
Career path to lab manager or optician
BLS's advancement picture runs through the large facilities: lab technicians may move up to supervisor roles and train new technicians, and some go on to own a laboratory.
BLS's Employment Projections for 2025 to 2035 — a count that includes self-employed workers, unlike the OEWS payroll figure — project the occupation going from 18,600 jobs in 2025 to 19,000 in 2035, a 2.2% increase, with about 2,200 openings a year.
The other direction is across the shop, into dispensing.
The two jobs are distinct, and the state line between them sits in different places: Connecticut licenses producing and mounting lenses as well as fitting them, while South Carolina's tested lens-processing skill excludes wholesale surface grinding.
If you are weighing the move, confirm your state's optician requirements with your state's optometry board or opticianry board.
If you run the lab or the optical instead of job hunting, the hiring hub is where eye care employers post an optician job and their other openings.
