My vision has gotten slightly worse each of the last 2 cycles I've ran. They were basic too, test c and dbol for one and just plain ol' test e for the other. My prescription for contacts proved there was a change too. And what was weird is that it was mainly my left eye both times. It wasn't much of a change, but I was wondering if any of you would have an answer as to why? I've had a couple of appointments with the eye docs to check stuff out and they said everything looked fine.
