MANMED says for entry into a program that leads to a commission in the USMC, you must be correctable to 20/20 for distant and near visual acuity.
The other issue with your vision is to figure out why you’re not correctable in that one eye. That condition itself (eg keratoconus, cataract, etc) may also be DQ. One last piece is you may have some issue with depth perception with one eye being 20/10 and the other correctable to only 20/70.
There are refraction standards too that you need to take into consideration with not being correctable to 20/20. Maybe you have lots of astigmatism?
It's a condition known as amblyopia, which is due to abnormal vision development. It's basically an astigmatism, but I see just fine even without glasses. It would've been correctable as a child, but my pediatrician missed it because apparently she only checked one eye so there's that. Also, I've been playing tennis for pretty much all of my life so depth perception isn't really an issue. Why does DoDMERB contradict MANMED?
DODI 6130.03 allows for the services to come up with their own criteria. DODI is also used for enlistment, not just for those coming in to be commissioned.
DODI 6130.03 page 14 says the following:
"b. For entrance into Service academies and officer programs, the individual DoD Components may set additional requirements. The DoD Components will determine special administrative criteria for assignment to certain specialties."
The USN has set additional requirements for visual acuity and codified it in MANMED.
My friend who used to be a physician reviewer at DODMERB told me they had cheat sheets at their desks they used for reference because vision standards were different depending on the service. Not all services use DODI 6130.03 for vision.
Amblyopia (aka lazy eye) is really your eye not working as it should. One of the causes of amblyopia is strabismus. Do you have that? That's where your eyes aren't aligned.
Most likely, you have refractive amblyopia. Do you have your latest eye glasses prescription? You probably have hypermetropia (farsightedness) in the one eye.
