RE: How good are their eyes?
No, don't worry about spraying your turkey huntin clothes with UV killer, turkeys can't see UV. It all has to do with the rods and cones issue. Deer see much better in low light conditions, which is when UV tends to glow. Turkeys can't see squat in low light, so UV isn't an issue. About the hat, it's a sharp lookin hat and I'd say wear it, it's not enough to draw attention to a turkey's eyes. There's orange and brown and yellow leaves all over the ground, brown limbs and all sorts of colors in the woods. That little bit of orange will not keep you from killing a bird. The main thing is to break up your outline and choose a good base color or shade of camo. Before the woods start greening up in the fall, I will wear something with no green in it at all, like realtree hardwoods or mossy oak bottomland. You don't wanna be sitting in bare woods looking like a big green blob. Once it greens up I put on the obsession. You can always stick some limbs and leaves in your hat too. Wear the hat.
