Thanks to advice I found on here and elsewhere, I think I have my situation resolved. Apparently for a civilian coming off the street and going through the process trying to a FC1 at Wright-Patt, everything done in MEPS is supposed to be a one-time screening process and is supposedly non-waiverable. However, in my case, I went to a civilian optometrist and found out that I needed a pair of glasses because I am farsighted in one eye and have astygmatism in the other. Due to the fact that I needed glasses and was unaware of this when I went through MEPS, that warranted getting my eyes re-tested. So I went to my sponsoring unit's base, and got retested for everything and passed the DP test with a perfect score. I am so grateful to the advice I got on here, not only in regards to a possible appeal process, but also on how to take the test effectively. The first time I took it at MEPS, I assumed it would be a cake-walk, so I went through it really quickly, and did not take my time and try the focusing techniques mentioned on here. Once again, thanks for all the advice and suggestions, baseops forums are an awesome resource for people trying to get to UPT.
