Shooting with both eyes open will give you a clearer picture of the target or animal. You will be able to see the definition of the target better and pick a more precise aiming point.

After shooting with both eyes open forever I recently had to go back to winking because I was starting to get double vision after only a couple seconds of aiming. If I were shooting at a dot, it would actually split into two dots and slowly spread farther apart. The only way to fix it was to wink. I was told it has somethig to do with a part of your eye losing its flexability and causing the eye not to focus on two things at two different distances. Anyway, after shooting both ways I would suggest both eyes open if your body lets you. And for those of you who say you would never go back to winking, just remember, it may not always be your choice.

I hate winking to shoot, but someone would have to jab both my eyes out to get me to quit shooting.
