They may sound like different situations, but for, me they're related.
I have lost most of the vision in my right eye due to not paying attention to warnings about glaucoma.
I am left dominant:  handed, footed,and eyed.
I have always used a semi-auto rifle, from my first to the two I now own.
I probably will never use them again because of no longer having adequate vision in my right eye.

As I see it, I now have two choices.
1.
I can outfit my older model Redhawk 7-1/2" .44mag with a Weigland Mount and scope to use it for hunting.
Because of carrying it for bear protection when living in AK, I taught myself to use it left-handed because of being left eyed.
I ran a lot of ammo through it before it  became natural for me.
I can group into a 5gal bucket lid at 100yds shooting offhand through iron sights.

To hunt with it, I would need to mount a scope on it.
My old bandolier style carry will not fit it scoped.
I really like the way that carry rode on my chest, comfortable, quick and easy to draw.
I'm having a hard time finding a carry that will ride like the old one does, in the middle of my chest with the grip at about armpit height.
I really don't want to get a spendy fancy leather holster.
It's just going to be a beater hunting holster.
Suggestions?

2.
Then, I've been considering using a crossbow.
It would be much easier to learn left-handed and much less costly in expended ammo and buying a left-handed rifle.
I do not like the idea of using a semi-auto left-handed.

 The use of a crossbow is confined to hunters with a disability.
Per regulation, and the crossbow waiver's wording:  to use it in public hunting areas, a disability waiver is required.

To be honest, I don't want to use it in public hunting areas.
I've planted several fruit trees that are beginning to bear fruit.
Many nearby neighbors complain about pigs tearing up their yards.
I want it in case pigs begin coming into the yard for fruit on the ground.

So far, I've not had the problem.
If and when I do, I would prefer a crossbow to a .44mag.
I think the neighbors would agree.

Anyway, I've asked a physician about it.
He seems to be very reluctant to give it..
He doesn't refuse to give it, but keeps giving me B.S. put-offs, neither yeahs or nays.
I think it's a personal problem with the subject.

Has anyone dealt with this, or has informed suggestions about dealing with it?

 

How does blindness in the right eye prevent you from shooting left handed?

From my post:
"...  It would be much easier to learn left-handed and much less costly in expended ammo and buying a left-handed rifle.

It doesn't.
But, it would  require me to relearn the use of a rifle left-handed as opposed to a lifetime of right-handed  use.
I have never fired a rifle without  having to close my left eye to sight it.
That's just the way I learned as a kid.

It took thousands of rounds to learn to shoot the Redhawk left-handed comfortably.
That was in Alaska where you can use firearms just about anywhere.
That is also why I began reloading my ammo.
I don't see my being able to go out and put thousands of rounds through a rifle to become proficient with it anywhere in Hawai'i.

EDIT:
Over the years, I have tried using a semi-auto left-handed many times.
I've always ended up getting hit in the face by ejected casings.

Alright I got it now, you learned to shoot right handed even though you're left handed and left eye dominant.  That's odd.

AR15/AR10 rifles have brass deflectors that kick brass to the sides so it wouldn't affect you.  Use a red dot scope so you can keep both eyes open and it's good for short range, 100 yards.  You have the benefit of being left handed/eyed so it shouldn't take too long for you to be adequate for shooting and manipulation.  I'm right eyed/hand dominant and sometimes train left handed, I don't do it very often but I'm adequate.

Not really.
Welcome to the world a left hander  has to live in.
All through my younger years, people were trying to force me to use my right hand.
The only things I do left handed are the things I learned on my own without interference from others.
I am not going to buy another rifle.
And there is a lifetime of muscle memory for shooting right-handed.
Relearning would be a major effort that would be very difficult here with the firearms regulations.
... thousands of rounds ...

Because of my vision limitations, I believe I should qualify for the dispensation so that I can use a crossbow.
If not, I'll use the .44.

My grandfather had a stroke and lost much of the vision in his right eye. He was able to get a scope rail that offset his scope to his left eye. I believe it was a custom job at the local gun shop but I have to assume there are commercial ones available. Sure it looks goofy, but he’s 85 and still gets to hunt. The shop is Toli Arms LLC in Colfax Wisconsin if that would be something you are interested in. (No I’m not affiliated with them.)
