This hasn't happened at the range yet, but when I'm practicing at home, I'm finding it harder and harder to focus on the front sight.  It's not that I can't focus, exactly, but that the image from my non-dominant eye is getting more and more pronounced, so what I see is the front sight standing beside the rear.  When I close the non-dominant eye, it turns out I have perfect sight alignment, so it's not throwing my aim off.  And when i do the dominance tests, I keep landing on the same ol' dominant eye that I always have. 

Lighting in my house isn't all that bright in the evenings when I practice, which may be the reason.  But I am getting to that certain age when vision changes are often reported. 

Solution.


Don't play with your guns when you're drunk.



Tada 

Tom, any eye surgeries?  Lasik etc.   I had an opthomologist in my class the other week and I was talking to him about eye stuff and age etc. was kind of cool!

I had lasik a while back, over 10 years ago.

We had an "older" guy in the class last weekend who was former military and knew what his dominant eye was. When we did the dominant eye test, he found his dominance had "changed." Couldn't explain it...didn't have any surgeries, strokes, head trauma, etc.

I had lasik a while back, over 10 years ago.

I think the guy told me that when they do lasic, one eye can change because they map the focus differently?  Or both eyes could work simultaneously since one mapped far, and one is mapped near?  I know that you can have dual focus with lasic is what he explained to me.

It presented an interesting discussion.

I'm cross dominat but its funny how the body adapts. I trained to shoot with my non dominant. Was a bitch. Broke my dominante hand really bad once and was in cast and rehab for close to a year so Iearned to shoot pretty good with my non dominant hand and dominant eye. Now I can shoot both hands and eyes with almost the same accuracy. I didn't plan for it to turn out that way but am glad for the results. I actually favor my non dominant eye. Crazy huh? 

Dominance can shift with age, fatigue, injury, repair or even sickness.  I am actually ambi-ocular which is either good or bad.  I have no real dominant eye, thus they often fight one another for dominance.  Or dominance can shift throughout the day.  This makes shooting with two eyes open a very difficult task, to near impossible for those less than 3% of the population with that type of vision.  On the upside, I can force dominance very easily with a mere squint and shoot very well with either eye and is a good advantage to support side shooting especially with a long gun.

What happens with your vision that makes it more difficult while you are shooting? I guess how does ambi-occularness (is that a word?) physically affect your sight picture.

I had the same problem awhile back. Try wearing an eye patch for a few weeks while you practice or just around the house. It'll force your brain to make the adjustment to your dominant eye.

Due to human binocular vision we only have a single focal point. when attempting to shoot two eyes open we naturally have two images of an object that is not our focal point.   One image is true and one is a ghost image.  When we target focus the eyes see two front sights and when we use front sight focus we see two targets.  One image is true and one is not.  We can easily learn which image is correct by understanding which eye is dominant. For myself both eyes may battle for dominance and both images can reverse quickly while aiming.  The visual input is hard to describe but imagine those two images flip flopping literally at the blink of an eye.  Or one eye might have more dominance than the other at any given time any which means that you cannot consistently train yourself which image is true and which is the ghost image as dominance changes.

Ambi ocular is rare and many who might be may never know it.  Many shooters who may be ambi ocular may not understand it themselves and even fewer instructors will understand it and / or diagnose it correctly.  Shooters may be accused of being stubborn or hard learners when it comes to traditional methods of teaching two eye open shooting. 

Advanced shooters with this problem will force dominance by squinting or closing one eye in that millisecond when breaking their shots.  Some might use the traditional argument that it cuts down on peripheral vision and situational awareness.  In reality shooters are so threat focused at those moments in time that true peripheral situation awareness really does not happen.  Also many advanced shooters in this category will shoot two eyes open up close as body mechanics, natural point of aim and skill weigh in heavily and true hard frontsight focus is of lesser importance.

If this is correctly diagnosed by an instructor, lesser importance should be placed on two eye open sight alignment / sight picture and development of forcing dominance via squinting or closing one eye becomes of greater importance.  As shooter skill develops two eyes open will become the norm when engaging closer targets or targets with a more forgiving hit zone as other skills for non sighted alignment via mechanics weigh in heavily.  When more precision is needed generally the situation is not harmed with closing or squinting an eye.  In other words accuracy trumps speed.  So when instructed or trained properly the shooter will overcome any difficulties with correct practice of their modified technique.  Again when addressed properly it becomes a non issue.  However many instructors who don't understand and correctly diagnose the problem 99% of the time exacerbate the problem.

Yes, laser refractory surgery can make one eye good for distance and one for close, but the guy I mentioned hadn't had surgery.....

Thank you Brother!

Could be a tumah..........

It's not a tumah

Oh, Ahnald!!
