Actually binocular vision doesn't help - I almost always close one eye when threading needles. I need to wear reading glasses now though, getting too old to see small stuff clearly enough. (I cheat - I got some extra strong reading glasses for close work like threading needles and removing splinters (3 diopter, normally use 1.0 to 1.5 for reading) - they are a big help.)
