How's your eyesight? Not trying to be a smartbutt.... If things are getting fuzzy then it is easier to see them once they are moving. I agree with the posts saying the more game you see, the easier it is to pick them out.
Hunt with your eyes, not your feet. Slow down and LOOK.
I allways look as far ahead as i can and grid back to me . I never find stuff and trip over sheds . look for horizontal lines , ie ears and back line . when I glass I start in one corner and grid check then repeat from a differnt side .
