Here’s some context, in a life and death situation you will naturally have both eyes open out of fear. You may even have tunnel vision so train with both eyes open because that will be your default vision when  the SHTF.

I shoot with both eyes closed momentarily

Red dot... Both eyes
Irons... One eye.
At least thats what works for me

Being right handed and left eye dominant it is pretty much impossible to use iron sights with both eyes open.  But red dots are not a problem for me.

If I had a third eye, it would also be open too

I feel no eyes open shooting is the most accurate.  That way I’m certain to hit what I’m aiming at.

I shoot with both eyes closed.

I’m right handed and left eye dominant. My work only uses iron sights. On the range, I find myself closing one eye when shooting from 25 yards and both eyes open from 3-15 yards.

One eye for competition , both eyes close for self defense  !

Thank you for the tips have ben shooting for 65 years
My eyes are getting old
Never to old to learn😊😊😅😊😊

Got it both eyes open and usr two guns at once .
That way you cant miss one for each of the targets you see in double vision .

You're the best teacher i've seen on You Tube ! Everything is explained clearly ! You're the best bro !! Just what i needed ! Supreme job !!

Another reason to train with both eyes open is because, when presented with an actual threat, your body might override your single-eye training and make both eyes wide open - fixated on that threat.  In that case, being able to aim with both eyes open would be a big plus.

Wow! Squinting has helped me IMMENSELY! I always saw double and knew which sight picture to use (or split the difference). This was a game changer. Thank you!

I was helping a friend learn to shoot using iron sights. I told him to leave both eyes open. His aim was terrible. Eventually he started to practice with one eye open and his aim improved dramatically. It seems he was using the front post with his left eye and lining up with the notch at his right eye...I've done this too in the past. Now if I can get him to stop flinching... :)

Your videos are very informative. I have been shooting for over 50 years and the way you present these is great for new shooters.

I have used both eyes for years with iron sights on pistols, and always struggled with inconsistent accuracy. I started closing my non dominant eye, and my accuracy improved massively.

I started my Marine life with equal sight in both eyes and learned to be a rifle and pistol expert on both the range and combat course. Crossed rifle and pistol badges for five years. Shrapnel ruined the vision in my right eye. I had to learn to shoot left-handed. Regained my expert range badges left-handed. Never mastered the combat course again. The lack of vision in my right eye slowed my response time, and cyclops does not do so well for target acquisition.

Many years ago as I walked to the mailbox a huge Rhodesian Ridgeback came at me full speed barking and growling. I quickly pulled out my gun. I know dogs don't know what a gun is so I suppose the dog sensed something wasn't right and stopped just a few feet in front of me barking/growling and repeatedly making movements like he was about to lunge everytime I tried move back towards my home. I aimed at the dog with one eye closed. As I was about to squeeze the trigger the female owner ran in front of my site picture and grabbed the dog by the collar.
We exchanged some un-neighborly pleasantries. I called the law as I walked back to my home and so did she. The constables showed up. District attorney was called. I was no-billed because it was a clear case of self defense. The dog owner received a fine. The incident scared me because that almost got shot. I believe my circumstances would have been drastically different if that had happened.
I immediately changed decades of shooting with one-eye to both eyes open. One-eye shooting and fear had me focused with tunnel vision on the dog and nothing else. I never seen the woman until she was directly in my sight picture. The District attorney I believe would have had a field day prosecuting me. Fortunately I ended up on the winning end.
PLEASE, PLEASE, PLEASE learn how to shoot with both eyes open. It may keep you from making an innocent mistake.
