TR,
I agree 100% with the reasoning behind the standards. I am also positive I will have eye surgery at some point in the next few years. My goal for right now is to get in and put myself into a position to achieve my goals somewhere down the road. What I do find interesting is that while my vision is bad, I do already meet the requirements for a "2" on the eye portion of the physical,

which is what 18x requires. However, I have not actually taken the physical at MEPS.
"E" Position - Vision–eyes (5th number in the profile series) - Visual acuity, and organic disease of the eyes and lids.
1 - Uncorrected visual acuity 20/200 correctable to 20/ 20, in each eye.
2 - Distant visual acuity correctable to not worse than 20/40 and 20/70, or 20/30 and 20/100, or 20/20 and 20/ 400.
3 - Uncorrected distant visual acuity of any degree that is correctable not less than 20/40 in the better eye.
4 - Visual acuity below the standards of "3."
