7412 vs 7120
Optometrist (USN) vs Aerospace Experimental Psychologist (USN)
Two rates that pass each other in the P-way daily and have zero comprehension of what the other one does for 12 hours.
What 7412 calls "another day at the office": the recruiter said 'you'll provide vision care to service members and their families,' which is refreshingly accurate. What 7120 calls "another day at the office": you have a PhD and you study human performance in aviation and aerospace environments — cockpit design, pilot selection, human factors in high-G maneuvering, spatial disorientation, crew resource management, and the neurological limits of humans operating machines that fly faster than sound. The word "office" is doing a lot of heavy lifting in one of these sentences. Two MOS codes that pass each other in the PX parking lot and have zero overlap in their professional lives.

The pitch versus what people who actually did the job report back.
“Navy Optometrists provide eye care to the fleet and Marine Corps with zero student debt through HPSP. You'll practice in state-of-the-art facilities, gain experience with unique occupational vision requirements, and build a clinical practice without the business overhead.”
You are a Navy Optometrist — a licensed Doctor of Optometry in uniform — which means every sailor who needs glasses, contact lenses, or a comprehensive eye exam will pass through your clinic, and that is a LOT of sailors because the Navy requires everyone to see clearly, and somehow sea duty accelerates every eye condition known to medical science. The recruiter said 'you'll provide vision care to service members and their families,' which is refreshingly accurate. Your patient load includes routine refractions, fitting military-spec protective eyewear, screening for conditions that could end a pilot's career, and telling Marines that no, they cannot keep wearing those scratched ballistic lenses from three deployments ago. You'll graduate from optometry school with a commission and discover that military optometry moves faster, sees more patients, and has more impact on operational readiness than any civilian practice — because a sailor who can't see can't fight, and a pilot who can't see can't fly.
“You'll work at the intersection of psychology and aviation — studying human factors, designing cockpit interfaces, and improving pilot performance. It's cutting-edge research with real operational impact, and the expertise is valued by NASA, FAA, and defense contractors.”
You are an Aerospace Experimental Psychologist in the Navy, which is one of the most niche designators in the entire Department of Defense and quite possibly the hardest to explain at a family dinner. You have a PhD and you study human performance in aviation and aerospace environments — cockpit design, pilot selection, human factors in high-G maneuvering, spatial disorientation, crew resource management, and the neurological limits of humans operating machines that fly faster than sound. The recruiter said 'you'll apply psychology to cutting-edge aerospace challenges,' which is one of the rare times a recruiter was entirely accurate. You literally research why pilots make errors and design the systems, procedures, and training that prevent them. You are the reason the ejection handle is where it is, the warning light is the color it is, and the heads-up display looks the way it does. Your work saves lives in ways nobody will ever publicly credit, and your conference presentations are attended by twelve people, all of whom have the same PhD.
The Real Life
Same dimensions, side by side. 7412 on the left, 7120 on the right.
Providing comprehensive eye care to active duty service members, dependents, and retirees — refractions, contact lens fitting, diagnosis and management of ocular disease, flight physicals (ocular component), and military-specific vision readiness screening. You determine whether sailors and Marines meet vision standards for their ratings and designators, which directly impacts operational readiness. High patient volume is the norm — military optometry clinics see more patients per day than most civilian practices.
Conducting human factors research in aviation and aerospace environments — cockpit design, pilot selection, spatial disorientation, G-tolerance, crew resource management, and human-machine interface design. You design experiments, analyze data, publish papers, brief program managers, and work with test pilots and engineers to improve aircraft systems based on human performance data. The work sits at the intersection of experimental psychology and aerospace engineering.
Requires a Doctor of Optometry (OD) degree from an accredited optometry school. Most Navy optometrists enter through HPSP (which pays for optometry school) or direct accession. ODS at Newport, RI is 5 weeks. No additional military optometry training — you enter as a fully qualified clinician.
Requires a PhD in experimental psychology, engineering psychology, or human factors before commissioning. No military psychology training pipeline — you enter as a fully qualified researcher. Officer Development School (ODS) at Newport, RI is 5 weeks of basic military orientation. The community is very small — fewer than 50 billets Navy-wide.
Low. Clinical optometry is office-based. Standard Navy PT requirements.
Low. Research and academic work is office and laboratory-based. Standard Navy PT requirements.
Navy Optometrist is a straightforward clinical career in uniform: you practice optometry, see a high volume of patients, and provide vision care that directly supports military readiness. The HPSP scholarship makes this financially attractive — debt-free optometry school in exchange for military service. What they won't tell you: the patient volume is very high (military clinics run fast), the equipment may not be as current as a well-funded private practice, and the administrative burden of military medicine adds overhead to everything you do. The most unique aspect is operational vision screening — you determine whether someone meets the vision requirements for their job, and for aviators and special operators, your clinical findings have career-ending implications. The civilian transition is seamless: you're a licensed OD with high-volume clinical experience. Private practice, VA optometry, and corporate optometry all value the throughput and diagnostic experience you develop in military clinics.
Aerospace Experimental Psychologist is one of the most specialized and least-known designators in the Navy. You need a PhD before you start, the community has fewer than 50 billets, and most people in the Navy have never heard of you. The recruiter certainly didn't mention this option — you probably found it yourself through academic channels. The work is genuinely fascinating: you study why pilots make errors, how cockpits should be designed, and what the limits of human performance are in extreme aviation environments. Your research directly influences aircraft design, pilot training, and safety procedures. What they won't tell you: the community is so small that career management feels personal (for better and worse), your promotion path is slower than URL officers, and you will spend a significant portion of your career justifying your existence to operational commanders who don't understand what experimental psychology contributes to aviation. The civilian transition is seamless — FAA, NASA, defense industry human factors roles, and academic positions all value this exact background.
