The grinch detector seems to be working well here.
They ought to have abandoned leap seconds in the year 2000, which would have made a dandy new epoch, and simplified all date calculations for a millennium or so. There is absolutely no reason to inflict leap seconds on civil time; the amount I'm off from the center of my current time zone already introduces more error than that. It's just not important to anyone but astronomers or masochists. Well, and maybe sadists (especially standards wonks).
Sorry, that's bogus. I spent 14 years blind in one eye, in the middle of my life. Yes, there are many tricks that you can use to compensate for lack of binocular vision, and I learned most of 'em, but it is not the same, and I missed my stereoscopic vision terribly. I was fortunate to get my stereo vision back with a cornea transplant, and have never taken it for granted since. Integrating a 2d video signal over time is much harder work for your brain than the relatively instant and effortless 3d awareness that binocular vision can provide when stereo fusion is achieved. If it's not there, it's just not there, and there's only so much you can do to compensate.
