When growing up, I was always taught to shoot with one eye closed. Always shot rifles that way and that just transfered to shooting my bow that way. Then, I came across a movie that you all probably have heard of "American Sniper". Somthing I noticed that he shot with both eyes open. So that got me intrigued and I started looking up shooting my bow with both eyes open. I was then greeted with just exactly how many people shoot with both eyes open and how much more accurate you are supposed to be. So at that point, I wanted to watch the top shooters shoot and low and behold they mostly are all shooting with both eyes open.
I then started do more research and then tried it myself. Hmmm.. yea, that didn't work out to well at first.
First arrow, totally missed the target.. Second arrow, totally missed the target....again.
Then, the third arrow hit the target, but I saw something I never saw before. The actual flight of the arrow. That was something that was soo entirely cool and new. The release felt good, solid, but the arrow hit the target right where I was looking, not the middle but right where I was looking. It was at that point that I decided to re-train myself to shoot with both eyes open. This required, quite a bit more work, then I originally thought at the time, but now at this point, being a year later of shooting with both open. I can certainly say that so long I can shoot this way, I'll stay shooting with both open.
Moving to this method was much harder than originally thought. The reason for moving for me was after researching this topic, it was noted that first during hunting with target aquision. When the animal is moving, shooting with the single eye open, trying to see both the sights and target the field of view is reduced by over half. Then, when shooting at an animal with it being later in the evening (still during legal shooting hours), you will allow for more light into the eye for aiming and target aquisition.
The next part to this, is the way the body works. This is something totally natural for the body, when looking at and aiming wih both eyes. You have the sights of the bow with typically the dominiate eye, then the second eye has the target. The body has the natural ability to bring all this information together and processing it for you and for your body to understand. This is something that is completely natural to your body, then if you think about it. You do it naturally quite often everyday. You probably just don't realize it. When shooting with a single eye open, it takes much more coordination for the eye and body, then processing in the mind takes more time in this scenario as well due that it is not a normal process for the brain. Everything is in 2-d for the brain to process and with a single eye the idea of depth perception is gone.
So at the end of the day, if you are shooting with a single eye open, comfortable and happy with your accuracy, then your probably not one to change the ways (if it works, then don't change it). If you're looking for a more accurate way of shooting, then trying to super tune your bow (another blog post on that at another time). Then perhaps shooting with both eyes open is something you should try. I can tell you one thing, you will see the arrow better and if released correctly, you will see an awesome sight with watching the flight of your arrow all the way to the target.
