I posted a video of me shooting a full 300 indoor Vegas round live with the camera close up to show my form and it spurred a lot of questions. One of the most common questions asked was why I closed one eye but then opened it up again during my aiming sequence?

This process of closing my left eye and then opening it again is something that I learned to do to help me confirm that my peep and sight housing are perfectly aligned. I have found that in some shooting conditions, your eyes can adjust differently and give a variance on focal points or even dominancy. The fact is, your eyes gather more light when they are both open so you do want to shoot with both eyes open. This can be difficult if you have always shot with only one eye open.

Early on, when I was learning this process of shooting with both eyes open, I had to train my eyes by using a blinder clipped to my hat for many years until my right eye learned to take control when both eyes were open. Eventually, I no longer needed to use the blinder. I grew in the habit of drawing back and looking at the target with both of my eyes open. As I’m settling into my peep, I slightly close my left eye so that I can guarantee that my right eye is in charge and my peep has a perfect eclipse around my sight housing. Once I see my perfect sight picture, and I have my pin on my aiming spot, I relax my left eye open again so that I can see a brighter overall picture. For me, this has become my TWO, ONE, TWO process. If you are currently shooting with only one eye open, give this a try as you work on getting to a point where you can shoot with both eyes open, which will allow you to be more accurate and consistent with your shots. 

Shooting with both eyes open allows your eyes to gather more light creating greater visibility of your target.
