20-15 after Lasik but even great eyesight doesn't spot game. Being able to see animals like deer in the wild is an acquired skill. I used to spend a lot of time still hunting in typical New England terrain so I had to learn what to look for and where. Rarely do you spot a deer before it sees you if you are looking for a whole deer. Picking up a leg, twitch of an ear, a bit of white out of place or the line of a back is something that catches my eye. Basically I am looking for parts of a deer or something that doesn't go with the view I am seeing. Once you get it dialed in the deer seem to just pop up. I use a pair of 8 X 32 and 10 X 42 depending on how thick the woods are for spotting. When you go slow and glass ahead sometimes you see those deer parts pretty easily.
