I don't have binocular vision. I lived aboard a sailboat for a few years. I'm quite active with rock climbing etc and I honestly don't think I would be able to do anything better if I had binocular vision...

Just a thought

Good for you!

But I know I am worse doing climbing etc. with one eye.

It is probably something you can train and get used to, that it is not such a big deal, but I cannot imagine doing it on the same level one eyed.

But then again, you did not have enough motivation to spend time learning it. A pirate captain might have enough to actually train this way.
