These are way too strong. . . . For way too strange a drawback.
The one handed trait is simple: You lose two hand. You can't dual wield. You get +5 base hit.
These are severe drawbacks for a minor boost, for someone who wants to roleplay as having one arm, or lost it anyway.
(Or I guess, for someone using a tome and an indignant idol its kinda free, which is lame, but whatever. Its only +5 hit on a weapon type that has no parts.)
Or more problematic, Bows. Which really did not need that hit boost. Frankly I feel like it should negate bows in the first place!
But I got off topic.

Basically if you wanted a one eyed trait, I don't think there'd need to be two seperate ones. And I also don't think it'd need to have such huge buffs or such strange drawbacks. Having one eye should nerf your hit against far away foes, and potentially increase your farshot penalty. But increase hit by 5 against targets just next to you. As having one eye messes with depth perception.

But then it has the issue of just being taken up by every dagger/melee fighter. . . . Either way and regardless: +10 crit and +15 critical damage multiplier is far too much for a trait to give.

A totally blind trait could be a neat idea.
