How bad does your eye prescription?

Q. How high does the negative numbers go on eye prescription? Would -5 or -6 be considered bad? And if you qualify for laser eye surgery, is your vision instantly improved? is there a chance it could go back and get worse

A. As far as I know, the lowest a negative number can get on an eye prescription is -8 but I don't know the highest. -5 or -6 would be considered as medium myopia/nearsightedness. Yes, if you get laser eye surgery, your vision becomes clear and perfect again. No, not that I know of - for most people laser eye surgery makes their eyes permanently clear for a lifetime, no more nearsightedness.


How bad can your be to still be able to be in the Air Force?
Q. So I want to be in the air force. But my eyes are at -4. I wear contacts that bring my eyes to 20/20. What is the cut off for how bad your eyes be before you cant be in the US Air Force/fly the planes? Can you do Laser Eye surgery to fix your eyes? Why do you have to wear glasses while in boot camp???

Thanks!

A. The max is + or - 8.0... Im not really sure how the vision scale works (I've never had vision problems) so idk if you fall within that. However, that is just to enlist, certain jobs (probably pilot) require better vision.


Will the Navy admit me into their aviation program if I've gotten laser eye surgery?
Q. I'm applying for Naval OCS after I graduate from my university this year. I want to either be an aviator or go into their engineering program. The problem is that I don't have perfect eye sight and I'm getting laser eye surgery after graduation. Besides that, I'm perfectly physically fit and academically capable (double-major in applied math and mechanical engineering w/ 3.8 gpa)...

A. You'll need a waiver because it's a medical disqualifier. I don't think they will let you fly. You'll also have to wait a year before you can join, if I remember correctly. My hubby got LASIK after getting out of the USMC, then needed a waiver for it when he joined the USN a year later.


Can I become an army helicopter pilot if I have lasik eye surgery?
Q. My uncorrected vision is very bad, over 20/200 I believe. I realize that the worst uncorrected vision you can have to become a helicopter pilot in the army is 20/50, but If I get lasik eye surgery which corrects it to 20/20 would I be eligible for flight school?

A. You are correct in that your uncorrected vision is too bad for you to be a helicopter pilot in the Army as is. However, you are also correct in that you can get LASIK surgery and still be eligible to apply if it corrects your vision to 20/20 or better.

The other poster is incorrect when he says that you have to have 20/20 uncorrected and that you cannot wear glasses at all to fly. You can and many people do. Once you finish flight school, your vision can get as worse as 20/400, but must still be correctable to 20/20. See AR 40-501, Standards of Medical Fitness which I have outlined and linked below:

Chapter 2
Physical Standards for Enlistment, Appointment, and Induction

2�12. Eyes

c. Cornea.

(1) Current or history of corneal dystrophy of any type (371.5), including but not limited to keratoconus (371.6) of any degree is disqualifying.

(2) History of refractive surgery including, but not limited to: Lamellar (P11.7) and/or penetrating keratoplasty (P11.6). Radial Keratotomy and Astigmatic Keratotomy is disqualifying. Refractive surgery performed with an Excimer Laser, including but not limited to, Photorefractive Keratectomy (commonly known as PRK), Laser Epithelial Keratomileusis (commonly known as LASEK), and Laser- Assisted in situ Keratomileusis (commonly known as LASIK) (P11.7) is disqualifying if any of the following conditions are met:

(a) Pre-surgical refractive error in either eye exceeds + 8.00 to - 8.00 diopters.

(b) At least 6 months recovery period has not occurred between last refractive surgery or augmenting procedure and accession medical examination.

(c) There have been complications, and/or medications or ophthalmic solutions are required.

(d) Post-surgical refraction in each eye is not stable as demonstrated by�

1. At least two separate refractions at least one month apart, the most recent of which demonstrates more than +/- 0.50 diopters difference for spherical vision and/or more than +/- 0.25 diopters for cylinder vision; and

2. At least 3 months recovery has not occurred between the last refractive surgery or augmenting procedure and one of the comparison refractions.
