I said eyes are not needed to catch fish, but I do paint eyes on all my baits. Why? because I like the way dotted eyes look on a bait. Bass are predators like cats, they react on instinct. If you wiggle your fingers under the covers a kitten will pounce and attempt to kill. If a lure wiggle past a bass it will hit it (not every time) but if the fish feels the bait is not eatable then its spit out. Just an opinion, not based on any facts just observation.
