Something that you may also want to try is to shoot with both eyes open. It's a little trickier at first, but in time (maybe a couple of weeks shooting regularly) you will become very accustomed to it. I've shot shotguns, rifles and my bows with both eyes open for as long as I can remember. There are many advantages to using both eyes....the most important is being able to see better in low light situations. Give it a try!
