Dominant Eye – Shooters Eye: You should always shoot with your dominant eye or shooters eye. This is your stronger eye and will be your main focus eye for sight engagement and sight picture. Some people can train each of their eyes to be a dominant eye, which can be used when you shoot either left or right-handed.
Shooting with Both Eyes Open: Too many times people will close one or the other eye when they are shooting a firearm. How you train is how you will react or shoot when you are placed into a stressful situation like a self defense shooting event. Opening up both eyes, while you practice or shoot a firearm, will allow you a better peripheral vision for target engagements, or for multiple target threats.
