An ophthalmic technician assists ophthalmologists by performing ophthalmic clinical functions — taking medical histories, checking visual acuity and eye pressure, running diagnostic tests, and giving eye medications.
Federal wage data counted 71,010 of these workers in May 2025, and IJCAHPO's COA, COT and COMT certifications form a three-level certification ladder.
This guide covers the work, the settings, the certification levels and the routes in.
What is an ophthalmic technician?
O*NET defines Ophthalmic Medical Technicians (SOC 29-2057) as workers who assist ophthalmologists by performing ophthalmic clinical functions, and who may administer eye exams, administer eye medications, and instruct patients in the care and use of corrective lenses.
O*NET flags the occupation as Bright Outlook, and it groups a familiar set of workplace titles under the same federal code: Ophthalmic Assistant, Ophthalmic Medical Assistant, Ophthalmic Technician, Certified Ophthalmic Technician (COT) and Certified Ophthalmic Surgical Assistant.
The shorthand ophthalmic tech is on that same O*NET title list; on a posting, "assistant" and "technician" can describe work in one federal occupation.
The vocabulary changes on the optometry side of eye care.
The American Optometric Association (AOA) uses paraoptometric for allied health staff trained to assist doctors of optometry — a group that includes opticians, contact lens staff and optical assistants — and draws a distinction between paraoptometrics and ophthalmic technicians and assistants.
The Bureau of Labor Statistics' Occupational Outlook Handbook has no profile for ophthalmic medical technicians; it describes medical assistants who work for ophthalmologists and optometrists inside its Medical Assistants profile instead.
What do they do?
O*NET lists taking medical histories, tonometry, operating autorefractors, phoropters and tomographs, axial length measurement, visual acuity testing, lensometry, giving topical ophthalmic medications and visual field testing among the occupation's tasks.
Further O*NET tasks reach into procedure support: measuring corneal curvature with keratometers, ocular motility and depth-perception tests, retinoscopy, cleaning or sterilizing instruments, assisting with procedures including surgery, and calling patients about post-operative recovery.
The top two skills by O*NET's importance ratings are both communication skills.
On O*NET's importance ratings for the occupation, Active Listening scores 66 and Speaking 56, ahead of Reading Comprehension (53), Writing (53), and Active Learning, Critical Thinking and Monitoring at 50 each.
Software is part of the toolkit.
O*NET lists eye-care electronic health record systems such as AcuityPro and EyeMD EMR among the technology ophthalmic medical technicians use, and flags Microsoft Office, Outlook, PowerPoint and Word as Hot Technologies in job postings.
Hours, in the survey data: in O*NET's work-context survey, 77% of ophthalmic medical technicians reported a typical 40-hour week, 14% reported more than 40 hours, and 100% reported a regular, set schedule.
Where a technician's work ends and the doctor's begins varies with the practice — the supervising doctor's field, the workflow the practice runs, and, in optometry settings, the state's delegation rules, which govern what a doctor may delegate to staff.
Where do ophthalmic technicians work?
The federal definition points at ophthalmology: the job is assisting ophthalmologists through their clinical workflow.
The wage data shows the occupation reaching further.
BLS's May 2025 Occupational Employment and Wage Statistics (OEWS) counted 71,010 ophthalmic medical technicians across all industries.
The same release keeps a separate industry row for NAICS 621320, offices of optometrists, and counts 22,900 ophthalmic medical technicians employed in offices of optometrists there — the federal data tracking how much of this occupation works inside optometry practices.
What a technician may do in an optometry practice is governed by state delegation rules, which vary.
Oregon's rule (OAR 852-020-0060) is one worked example: optometric physicians may delegate non-prohibited tasks to well-trained technicians under direct supervision by an OD or MD at the practice site.
The same rule reserves ophthalmoscopy, gonioscopy, final biomicroscopy, final refraction, and final prescription and treatment decisions to the doctor — and, separately, final tonometry for a glaucoma patient.
Technicians may instill medication as instructed.
OD-MD groups — practices where optometrists and ophthalmologists work as one medical team — sit on the ophthalmology side of that definition: the occupation assists ophthalmologists, and its task list includes assisting with procedures, including surgery.
The same job title can therefore describe work in a one-doctor optometry office or a slot on a larger clinical team in a group practice.
Ophthalmic assistant vs technician vs technologist: the levels
Eye care uses three titles that read like seniority bands: ophthalmic assistant, ophthalmic technician and ophthalmic technologist.
The federal system does not split the assistant and technician titles — O*NET groups them in one occupation, SOC 29-2057.
The certification system splits the field into levels instead.
IJCAHPO — the International Joint Commission on Allied Health Personnel in Ophthalmology, formerly shortened to JCAHPO, a name some of its documents still use — runs three core certifications: Certified Ophthalmic Assistant (COA), Certified Ophthalmic Technician (COT) and Certified Ophthalmic Medical Technologist (COMT).
IJCAHPO describes the three levels as a solid ladder for progressive career development.
One structural rule matters for anyone planning the climb: IJCAHPO requires a sponsoring ophthalmologist's signature on its COA, COT, COMT and OSA-ST exam applications, and words the work-experience hours as under the supervision of an ophthalmologist.
Work done only for an optometrist is not named as qualifying in those criteria.
If your hours sit in an optometry practice, treat it as an open question rather than a closed door: IJCAHPO offers special-consideration requests for non-standard backgrounds, and the practical move is to ask IJCAHPO directly how your experience is treated.
Titles on postings and letters behind a name are two different systems — an employer defines its own "ophthalmic technician" job in the posting, while the COT is an IJCAHPO credential.
How to become an ophthalmic technician
There is more than one way in, and the entry data is unusually explicit.
In O*NET's survey of the occupation, 59% of respondents said a high school diploma or equivalent is required for new hires, 27% said a post-secondary certificate, and 9% said an associate degree.
BLS's Employment Projections table names the typical entry education as a postsecondary nondegree award — certificate-level training in the clinical tasks rather than a bachelor's degree.
Read together, the two series describe an occupation people enter from more than one starting point: O*NET's survey captures what employers reported requiring, while the projections table names the education BLS calls typical entry.
Finish high school
A high school diploma or equivalent is the most common new-hire requirement in O*NET's survey, at 59%, with post-secondary certificates (27%) and associate degrees (9%) behind it.Learn the clinical tasks
Histories, visual acuity, tonometry, lensometry, visual fields and medication drops are the tasks O*NET lists. BLS names a postsecondary nondegree award as the typical entry education, and the survey spread — 59% reporting only a high school diploma required — leaves room for employers that train on the job.Certify up the IJCAHPO ladder
COA, then COT, then COMT. Applications for these credentials require a sponsoring ophthalmologist's signature, and the experience hours are worded as under an ophthalmologist's supervision.Apply where the work fits
Ophthalmology practices are the occupation's home base in the federal definition, the May 2025 count put 22,900 of these workers in offices of optometrists, and OD-MD groups combine both — read postings in your market to see which settings and task mixes suit you.
Two cautions from the data.
First, IJCAHPO's criteria are the authority for its own certifications — confirm current eligibility, exam and renewal rules with IJCAHPO before you plan around a level.
Second, employer requirements differ — the survey spread above shows three different answers to the education question — so treat a posting's own requirements as the ones for that job.
Confirm the rules before you apply
Ophthalmic technician pay and certification
The headline figures come from BLS's OEWS survey, May 2025, all industries: 71,010 ophthalmic medical technicians (SOC 29-2057) with a median annual wage of $45,570, or $21.91 an hour.
The 10th percentile earned $35,700 and the 90th percentile $61,940.
OEWS counts payroll employees, so the self-employed sit outside these numbers.
Setting matters to the number.
In offices of optometrists — the industry row labelled "ophthalmic medical technicians employed in offices of optometrists" — the same occupation and release show a median of $38,650 ($18.58 an hour) across 22,900 workers.
Demand has its own series.
BLS's Employment Projections program counts the self-employed as well as employees, so its baseline is not the same number as the OEWS count above.
For 2025 to 2035 it projects the occupation to grow from 72,500 to 88,000 — up 21.4% — with about 11,800 openings a year.
On certification, the map is short: IJCAHPO's three core levels are COA, COT and COMT, ordered from assistant to technician to technologist.
The wage figures above are for the occupation as a whole, not by certification level — compare pay by setting and employer, and treat any per-credential figure you see online with caution.
