Optometrist Job Description
Optometrists are primary eye care doctors who examine eyes for vision problems and disease, prescribe corrective lenses, diagnose and manage ocular conditions, and in most states prescribe therapeutic medications for eye disease. They practice in private offices, retail optical settings, ophthalmology co-management practices, and hospital-based clinics, and they serve as the first point of contact for most patients with eye and vision concerns.

Overview
Optometrists handle more eye and vision encounters in the U.S. than any other type of eye care provider. That's partly because they outnumber ophthalmologists significantly, and partly because most eye care needs are primary care needs — refractive errors, dry eye, contact lens fittings, diabetic eye exams, and early-stage glaucoma management — that don't require surgical expertise.
A comprehensive eye exam is more complex than patients typically appreciate. The optometrist is simultaneously evaluating the optics of the eye (the basis for the glasses prescription), the health of the anterior segment (cornea, lens, anterior chamber), the posterior segment (retina, macula, optic nerve), the extraocular muscle function, and the neurology of the visual system — all in a 20–30 minute encounter. Finding a subtle disc margin change suggesting early glaucoma, identifying an incidental choroidal nevus that warrants monitoring, or noticing arteriovenous nicking that suggests systemic hypertension the patient didn't know they had — these require clinical acuity that comes from both training and repetition.
Contact lens fitting has become more technically specialized. Soft lens fitting for straightforward myopia and astigmatism is routine; scleral lens fitting for keratoconus, post-surgical irregular corneas, and severe dry eye requires additional training and instrumentation. Orthokeratology for myopia management in children requires fitting skills, patient selection, and a monitoring protocol that most optometrists weren't trained in during school.
The business side of private practice is a genuine part of the job for practice owners. Hiring, managing optical staff, managing insurance contracts, and making capital equipment decisions are not clinical tasks, but they determine whether a practice is financially healthy. New graduates who open or buy into private practice typically underestimate this dimension at first.

Career outlook
Optometry's employment outlook is stable to positive. The Bureau of Labor Statistics projects above-average growth through the early 2030s, driven by aging demographics, growing diabetes prevalence (and associated diabetic eye exam demand), and expanding optometric scope of practice in many states.
The private practice sector is undergoing significant consolidation. Private equity-backed optometry chains and ophthalmology practices with optometry co-management have acquired a large number of independent practices over the past decade. For new graduates, this creates an employment path that didn't exist 15 years ago — working as an associate OD in a PE-backed practice with a guaranteed salary and no ownership risk. For experienced ODs, the consolidation creates succession options (selling to a PE group rather than finding an associate buyer) but also competitive pressure.
Geographic distribution remains skewed. Urban and suburban markets have saturated optometric supply in many areas; rural and underserved regions have persistent shortages. The National Health Service Corps and Indian Health Service offer loan repayment benefits to ODs who practice in shortage areas, and the total compensation packages in those settings — combining salary and loan repayment — can substantially exceed private practice income for new graduates carrying $200K+ in student debt.
Myopia management is an expanding practice area with favorable economics. Building a myopia management program — scleral lenses, orthokeratology, low-dose atropine management — requires additional training and equipment investment but generates ongoing revenue from a pediatric patient population. Practices that have built this specialty consistently report it as a differentiator in competitive urban markets.
For ODs who enjoy primary care relationships with patients across decades — watching a child grow up, managing a diabetic patient's eye health through their adult life — private practice optometry offers that continuity. For ODs who prefer variety, academic, VA, and hospital-based settings offer broader clinical exposure at the expense of practice ownership upside.
Sample cover letter
Dear Dr. [Name],
I'm writing to apply for the associate optometrist position at [Practice]. I graduated from [Optometry School] in May and completed a one-year ocular disease residency at [VA/Hospital] in June. My residency was heavy on posterior segment disease — I managed a high-volume diabetic eye disease clinic and gained significant experience with OCT interpretation, glaucoma monitoring, and AMD co-management with retina.
I'm specifically interested in your practice because of your contact lens program. I developed an interest in specialty lenses during my residency — we had a small scleral lens clinic, and I fit approximately 40 patients over the year. I'd like to continue developing that specialty in practice, and I understand you have an active myopia management program that I'd want to learn from your team.
On the medical management side, I'm comfortable prescribing and managing patients on topical glaucoma medications, running the monitoring cycle for suspect patients, and making referral decisions. I also completed a rotation at [FQHC] where I worked with a diabetic patient population, which gave me experience communicating with primary care physicians about retinopathy staging and follow-up intervals.
I'm looking for a practice where I can build long-term patient relationships and develop clinical depth, rather than the highest-volume setting I can find. The reputation your practice has built in [City] suggests that's the environment you've created, and I'd welcome the chance to discuss whether I'd be a good fit.
Thank you for your consideration.
[Your Name], OD
Frequently asked questions
- What does an Optometrist do?
- Optometrists are primary eye care doctors who examine eyes for vision problems and disease, prescribe corrective lenses, diagnose and manage ocular conditions, and in most states prescribe therapeutic medications for eye disease. They practice in private offices, retail optical settings, ophthalmology co-management practices, and hospital-based clinics, and they serve as the first point of contact for most patients with eye and vision concerns.
- What are the main duties of an Optometrist?
- Core duties include: conduct comprehensive eye examinations including visual acuity, binocular vision assessment, and refractive error evaluation; dilate pupils and examine the retina, optic nerve, and anterior segment using ophthalmoscopy and slit lamp biomicroscopy; and diagnose and manage ocular conditions including glaucoma, dry eye disease, diabetic retinopathy, and macular degeneration.
- What is the difference between an OD and an MD in eye care?
- Optometrists (ODs) complete a four-year Doctor of Optometry program and provide primary eye care — eye exams, glasses and contact prescriptions, and medical management of many eye diseases. Ophthalmologists (MDs or DOs) complete medical school plus residency and fellowship, and can perform eye surgery. Most optometry patients never need a surgical ophthalmologist; optometrists manage their eye health through routine care and refer surgical or medically complex cases to ophthalmology.
- What does optometry school require?
- Optometry school is a four-year doctoral program (OD) at one of 23 ACOE-accredited colleges. Admission requires a bachelor's degree with specific science prerequisites and competitive OAT (Optometry Admissions Test) scores. Clinical rotations in the third and fourth years cover primary care, ocular disease, pediatrics, low vision, and contact lens subspecialties. Students graduate with OD designation and must pass NBEO board exams to obtain state licensure.
- How does optometry scope of practice vary by state?
- All states allow optometrists to prescribe topical ophthalmic medications. Most allow oral medications for systemic ocular conditions. A handful of states have expanded scope to allow limited surgical procedures like laser vision correction and some injectable treatments. The trend over 30 years has been toward gradual scope expansion, and several states are actively considering additional authorizations.
- What is myopia management and why is it growing?
- Myopia management refers to evidence-based interventions — orthokeratology, low-dose atropine, soft multifocal contact lenses — that slow myopia progression in children. Myopia prevalence in children has increased dramatically globally, and high myopia carries serious long-term eye disease risk. Myopia management practices are growing rapidly, generate significant practice revenue, and require specialized contact lens fitting skills that general optometrists don't all have.
- Is AI changing optometry practice?
- AI diabetic retinopathy screening — FDA-authorized tools like IDx-DR and similar systems — is being deployed in primary care settings to identify patients who need optometry referrals. AI-assisted OCT analysis is flagging glaucoma suspect cases earlier. For optometrists, these tools are generating more referrals into the profession rather than replacing it. The diagnostic component of the exam is being augmented; the clinical judgment and patient relationship remain the optometrist's domain.
