I'm slated to graduate this summer, in NROTC and have a pilot slot. Went for my initial flight physical, eye doc told me my left eye was only correctable to 20/25 and very small chance LASIK would help. Went ahead and got LASIK anyways, long story short both of my eyes now see 20/15. I have to get another flight physical in May to recheck my eyes. I remember the charts from my initial flight physical being very difficult to see compared with where I went for LASIK and the lighting was dim. My question is, what can be done to ensure my eyes are performing their best prior to my follow-up flight physical? I've read that sleep & hydration are key factors, but any other advice is greatly appreciated. Additionally, are there exercises I can do for my eyes or charts I could be practicing on?
