There is a little device that non-traditionalists often use on shotguns that accomplishes the same thing. It is a long front sight that has a fluorescence when viewed from directly behind, but not with the "off eye", which is at an angle. They are usually either green or orange. Many people mistakenly put them on their gun for duck hunting in very low light thinking they will "help them see the front sight" better in very low light. This line of thinking is counter-productive to good shooting as it sometimes causes one to look at the front sight rather than at the duck.

It's real value is for those with a dominance shifting issue, like you mentioned, as it causes the proper eye, the one behind the rib, to "gain more traction" as you so deftly put it. They look like death eating a cracker to me, but they work for that purpose. I guess the ducks don't know the diff.

I've had my right eye checked by two doctors. It's not bad with my current prescription--other than for shooting. And a change in prescription won't help. But it's now so much better than it was prior to solving the macular pucker problem that I can't really complain all that much. I was just looking for an easy fix--like a stronger prescription. Unfortunately, both docs tried that with their little machine and it isn't the answer. But considering that before dealing with macular pucker, during a typical round of skeet (depending on background, light conditions, etc) I'd totally lose somewhere from 2-5 targets. I'd see them come out of the house and they'd then disappear. Now I'll very rarely maybe pick one up real late.

Guess I need to make sure that all the birds I shoot flush with the sky in the background.

My problem similar to crs. Right eyed and right shouldered all my life even though I am left handed. When right retina fell off the klutz doctor left a fold in it that blurred the eye badly. So I switched to left shoulder/eye and that was a big problem as my right was still dominant and had to wear a patch over it. Plus the combs on some of my guns were now on the wrong side. Then the left retina fell off and after three operations the eye is useless because of a dark layer at the back of the retina that scalping could not repair. So now it is back to the right eye that is now my only eye. I can't see well enough to hunt upland game any longer. Lucky to see my dog! Had to give up driving in fast traffic and at night. But I can still shoot deer using a scope and managed to bag a Tundra Swan last fall at 30 yds. This fall I hope to bag a few diving ducks if I can get them swimming in my decoys at 20 yds or less.

Stan's thingie is a variant of what is usually referred to as a "bead blocker".

And the extremely short version is that the dominant eye is not necessarily the eye with the best visual acuity, but the one with the "best" visual processing. This is very likely the issue with women who are much more likely to need some form of off-eye masking but who on formal testing are actually not much more cross-dominant than men.
Visual evoked potentials have shown that dominance is related to the difference in latency (speed of the impulse to the visual cortex) and amplitude (amount of impulse).

Obviously our wonderful brains CAN switch dominance if one eye is severally compromised.

thanks for your links, drew. i'm past 70, and started taking areds for the beginning of md in my right (master) eye about 1.5 years ago. my uncorrected vision is quite poor - in glasses since 1959 - at my worst i was 20/240 left and 20/280 right. i am still corrected to 20/20-30 in both, but with slightly better vision in left and possible md damage in right i can "see" potential for issues in my future.

the segment by dr. colo was quite interesting, and i caught his reference to central vision. once in a while i will look through the offerings on the english site https://www.gunstar.co.uk/. over the years there will be a rare offering of a double that is described as "central vision". makes sense that the brits would develop the most careful means of proper fitting, and the good doctor's explanation helps me understand what is at play.

These would be nice

I'll bet those guns kick into your cheek like a booger, especially when the left barrel is fired.

Since we're discussing eye dominance may I enquire about a related issue? When one has cataract surgery and lens replacement(s) there are three options for the lens set up, as I understand it. One can have lens for distant vision clarity in both eyes, close up vision clarity lens in both eyes, or one of each. A young lady I know who works at an eye clinic where these surgeries are done says that women get along really well with one of each, but that men, in general, have a much harder time adjusting to that. Obviously, eye dominance has to switch back and forth according to what distance you are viewing, allowing you to use the proper eye for close up and the other eye for distance. But it would seem that one's depth perception would be hurt badly, not having two eyes focusing on an object in order for your brain to "triangulate" and judge the distance.

However, another friend of mine, a man, had this exact set up and said he got used to it in a couple weeks. This would be the ideal way to have it, it seems, if you could be sure your brain could adjust to it. If it couldn't, well that's bad news.

Has anyone here had this procedure done, with different lenses in the left and right eye, and how did it go? Was depth perception negatively affected?

Best, SRH

The right eye problem sounds similar to macular pucker. Any chance that an operation can flatten out the fold? Of course when you're down to one eye, you want to make REAL sure that nothing worse happens to it.
