How to shoot with both eyes open is a popular topic among shooters. When forming a sight picture, there are many benefits of not closing an eye that range from accuracy to situational awareness. So there is the question of strategy. You lose half of your field of vision if you close one eye and leave yourself vulnerable to a second intruder or other hazards. So you owe it to yourself to learn how to do it with both eyes open, whatever shooting style you prefer.
Shooting with two eyes open
First of all, you’ll want to know which one of your eyes is the dominant one. There are a lot of well-documented ways of finding this out, and you can read more about it here. Go and figure it out, then keep reading.
Next, move up with your gun to the line, aim as normal, close your off-eye and take the slack out of the trigger with your finger, then open your off-eye and observe the sight picture. With both eyes open, you will have either two targets or two pistols in view, depending on what your focus habit is (front sight or target), but only one properly aligned sight picture.
You will have two targets in view if your focus is on your front sight. The target you should aim for in this case is the one on the side of your dominant eye (right target if you’re dominant right-eye). You can check this by blinking your off-eye.
Put another way, you’ll have two handguns in view if your focus is on your target. In this instance, the gun opposite your dominant eye will be the correct sight picture (left pistol if you’re right-eye dominant). You can prove that by blinking your off-eye.
Now, close your off-eye and open again, all while holding your focus on the target and your finger on the trigger. With both eyes open and while focusing on the correct sight picture, break the shot. Repeat this procedure approximately 50 times.
Refining your new skill
Next, repeat the procedure, but start with both eyes open and try to seize the proper sight picture instead of beginning with your off-eye closed. Blink your off-eye once or twice, then to confirm (and adjust if necessary). Once you’ve checked it, break the shot with both eyes open. Repeat 50 times, approximately.
You are on the way!
Even so, in one day, do not expect to move from a one-eyed shooter to a two-eyed shooter. Provide some time for the process to stick with you.
Now, use the second method when you go back to the range or while you’re doing dry-fire practise at home. Try to do so only when you lose track of the right sight picture, instead of blinking to confirm each time. In other words, cheat if you find yourself losing concentration.
In time, to confirm your sight picture, you will rarely have to blink, as your brain learns to concentrate solely on the correct sight picture. Start today and never backslide to one-eyed shooting again.
