I'm in agreement with all -
First and foremost, Jerry is right and I've said the same thing for years, confidence is half of catching fish! I can't tell you all of the goofy stuff I've thrown to prove a point to others about presentation (that is, providing the illusion to the fish that this thing at the end of the line is something they should eat)... most times it's about action of the bait, but sometimes, as Lamar stated, there can be an inverse relationship between water clarity and the gaudiness of the bait the fish will hit; so, color can make a difference. And as Igor mentions, false eyes exist in nature for a reason. I don't sell my baits, so I don't use eyes... and I definitely get my share.
The reason BS5 sells more baits with eyes isn't due to a 'pretty' factor, it is due to a confidence factor for the one buying. Think of all the lures bought through out history (except by collectors) - from the lure packaging of yesteryear, to the infomercials with the flying lure - they were all sold because the fisherman had confidence that THAT LURE would catch fish, not because they were a work of art.
The better the lure looks to the fisherman (in his view), the more likely he will buy it; the better the lure looks to the fish (in its view), the more likely it will strike... which ultimately comes down to presentation (movement and color)... I believe this goes for every specie, bar none.
