How to hire an optical lab technician: what to look for, where to find candidates and what to offer

An optical lab technician — BLS calls the occupation ophthalmic laboratory technicians — makes prescription eyeglasses and contact lenses, typically with automated equipment, and the government is explicit that the seat is not a dispensing optician. In your practice the seat is the bench: the edger, the tracer and blocker, the tint unit, the repairs, and the check a job passes before the glasses reach the dispensing table.

The hire earns its keep when the work you currently ship out is recurring and close to the dispensary: same-day repairs, rimless and drill-mount jobs, tinting, rush remakes. When those jobs are occasional, sending them out avoids the equipment spend and the payroll line altogether. Volume aside, the honest test is whether a bench would change what your optical can promise a patient the same day.

Scope the seat before you post it, because practice benches are built differently from production labs. BLS observes that in small offices and retail stores lab technicians may handle every phase of production, while in large manufacturing and wholesale labs they may handle only one phase. Your bench is the first kind: the hire to want is a generalist who can take a job start to finish, not a specialist who has run one machine on a line.

Know the market you are hiring from, too. BLS counted 18,660 of these technicians nationally in the May 2025 OEWS, and 2,580 of them worked in offices of optometrists. Both are payroll counts — the series excludes the self-employed — so the in-house practice bench is a small slice of a small occupation.

Whether the bench pays for itself is an economics question more than a staffing one — our guide to the in-house optical lab works through the equipment, send-out and turnaround tradeoffs. If you have not staffed a bench before, the career-side guide explains what an optical lab technician does across settings. The rest of this page stays on the hiring decision.

Write the posting around the work, not one title. O*NET's sample job titles for the occupation include Surfacing Technician, Edger Technician, Finishing Lab Technician, Lens Grinder and Polisher and Line Operator, and a strong candidate may have carried any of them. Name the setting — private practice, OD-MD group or retail vision center — the lab you run, and the equipment that sits on it.

• The lab and the duties. Say which half the bench runs: finishing (edging, mounting, tinting, repairs and verification against the prescription) or surfacing, or both. List the machines by name so candidates can tell at a glance how much of your workflow they already know.
• Requirements. BLS's baseline for the occupation is a high school diploma and moderate-term on-the-job training, and certification is optional — though employers may prefer a certificate or associate degree. If you train, say so; postings that demand years nobody has push exactly the candidates you want toward the wholesale lab down the road.
• The license line, where one applies. Requirements differ by state: Connecticut requires a Department of Public Health license to produce or reproduce ophthalmic lenses or mount them, so lab work itself is licensed work there. New Hampshire's opticianry law expressly exempts work performed by laboratory technicians. New Jersey licenses ophthalmic technicians — the state's term for optical lab technicians who grind, surface and mount lenses. Check your state board's current rule before you write the requirements line.
• Physical demands, described as the job's own. BLS notes technicians may spend much of the day standing or bending and may wear goggles, gloves or masks. Write what a shift on your bench actually asks.
• Schedule. BLS notes most lab technicians work full time and schedules may vary — post your actual hours, including Saturday coverage if the optical needs it.

Post the pay. The BLS Occupational Employment and Wage Statistics release for May 2025 puts the median wage for ophthalmic laboratory technicians (SOC 51-9083) at $39,300 a year — $18.89 an hour — in offices of optometrists (NAICS 621320), with the middle half earning between $35,810 and $46,020. Across all industries nationally the median was $39,460 a year ($18.97 an hour), running from $33,530 at the 10th percentile to $57,380 at the 90th. Both figures cover wage-and-salary employees only.

Setting moves the number inside the same release: the median was $43,270 in medical equipment and supplies manufacturing, $36,870 in health and personal care retailers and $36,570 in offices of physicians. Those are broad industry rows rather than any employer's rates, so place your setting and then price against the postings you actually compete with. Check your state's posting rules too. Washington's law (RCW 49.58.110, effective January 1, 2023) requires employers with 15 or more employees to disclose the wage scale or salary range and a general description of benefits in each job posting. Our research did not verify other states' pay-posting rules — confirm the current rule where you hire.

Screen against the half of the craft your bench actually runs. Finishing is the front of the lab: reading the prescription and the frame, edging the lens to shape, mounting it, tinting, repairs, and the final verification before the glasses reach the dispensing table. Surfacing is the back of the lab, where the prescription itself is generated into the lens blank. O*NET's surfacing tasks for the occupation include mounting lens blanks in the chucks of cutting, polishing, grinding or coating machines and setting those machines up. Its list also covers selecting lens blanks, molds, tools and polishing or grinding wheels to production specs, and positioning cutting tools to the specified curvature and depth of cut.

A practice finishing bench needs the finishing half at full breadth, because there is no second department to hand work to. A candidate from a large wholesale lab may arrive deep on one machine and thin on the rest — the opposite trade of a small-office generalist who has never worked at production volume. Decide which gap you would rather train and screen for the other.

Scenario prompts do the screening. Ask a finisher to walk through a job they ran recently, start to finish: what they checked before edging, how they handled a mount that would not seat, and when they would send a lens back. Ask what they verify against the prescription before a job leaves the bench, and what they do when a measurement does not match. For a wholesale candidate, ask which phases they ran personally and which they only watched — the answer redraws their resume in your favor or against it.

Treat credentials as a preference, not a gate. BLS says certification is optional for this occupation, though employers may prefer a certificate or associate degree, and some schools teach surfacing and finishing — so an uncertified candidate with strong bench references is a training decision, not a disqualifier. Keep the questions on the work: the EEOC says employers may not ask applicants whether they have a disability, ask medical questions or require a medical exam before making a job offer, but may ask whether and how the applicant can perform the job. Asking how someone holds up across a full shift of standing and bench work is a job question; asking about their health is not.

The craft itself is the career guide's territory — our pages on lens edging and finishing and lens surfacing cover it in detail. This page stays on what to listen for.

Start with where the occupation actually works. In the May 2025 OEWS, medical equipment and supplies manufacturing employed 6,310 ophthalmic laboratory technicians, health and personal care retailers employed 4,500, offices of optometrists 2,580 and offices of physicians 1,750. The two office rows are the smallest of those four, and manufacturing and retail employ the most — so the experienced candidate you want is more likely to be sitting on a manufacturing or retail bench right now than on another practice's.

• Wholesale and manufacturing labs. Medical equipment and supplies manufacturing is the largest of the OEWS industry rows above. A technician who wants a practice's pace and the breadth of running every phase themselves is your best experienced hire — the pitch is the setting, not the skills.
• Retail vision centers. Retail opticals run finishing benches too, and in the smaller stores their technicians may handle every phase of production. A retail bench tech already knows the handoff from bench to dispensary.
• Schools. Some community colleges and technical schools offer ophthalmic laboratory technology programs, and some teach surfacing and finishing directly. A graduate is a train-and-hire bet rather than a day-one producer, and the good ones know it.
• Your own floor. An optician or sales associate who wants off the front floor already knows your prescriptions, your frame board and your patients. The bench skills are trainable on your equipment.
• A board that lists only eye care work. See the optical lab technician listings candidates see, then read our guide to where to post the job for a channel-by-channel breakdown.

Write the ad for the work and keep it lawful. Federal EEO laws make it illegal to discriminate against applicants or employees because of race, color, religion, sex (including transgender status, sexual orientation and pregnancy), national origin, age (40 or older), disability or genetic information — including in job ads and recruiting.

Plan for the ramp BLS describes. The occupation's typical preparation is a high school diploma plus moderate-term on-the-job training — which means the training is expected to happen on a bench like yours, not in a classroom first. Build the ramp explicitly: shadow the current bench (or your wholesale lab's workflow), then run supervised jobs on your edger, tracer and blocker, then go solo with every job passing a verification step before it reaches the dispensary.

Treat your equipment list as the syllabus. Edgers, tracers, blockers and tint units differ by brand, and your lab or practice management software adds its own job flow — entering the prescription, tracking a job across the bench, recording a remake. A candidate who has run a different brand arrives with the concepts and needs your machine time; write both into the first weeks.

Give the seat somewhere to go. BLS's advancement picture is drawn from large facilities: lab technicians may work their way up to a supervisory level, train new technicians, and some go on to own their own laboratory. Your bench may be two people, but the principle holds: a lead-tech step, a say in equipment and lens-supplier choices, or cross-training into adjacent work gives a strong hire a reason to stay.

If you use a working tryout, pay for it. Under the FLSA regulations, work that is not requested but is 'suffered or permitted' by the employer is work time (29 CFR 785.11) — the rule that makes an unpaid working interview risky when a candidate performs productive work for an employer the FLSA covers. Our research found no DOL guidance written for eye care hiring specifically, so if your tryout setup is unusual, confirm it with the DOL Wage and Hour Division or employment counsel. Once the hire is on payroll, the FLSA overtime floor applies: unless an exemption covers the role, employees must receive overtime at not less than 1.5 times their regular rate for hours over 40 in a workweek. Hours cannot be averaged across two or more weeks — worth remembering when production spikes and the bench wants the extra shifts.

Write the whole thing down — the duty list, the equipment, the verification step, the ramp — and the same document serves as your posting, your interview guide and the new hire's training plan. When you are ready to post the seat, start from hiring for your optometry practice.

Whether lab work itself is licensed varies by state: confirm the current requirements with your state's board before you finalize a posting, and check wage, hour and interview questions with the DOL, the EEOC or employment counsel.
