That means all the brain power that a cone needs to recognize both multiple colors and multiple shades is focused on just one thing: contrast. That makes it much simpler to see shapes, which is an excellent thing when you're trying to avoid a predator in dim light. Eyeballs evolved to meet needs - and you're ignoring that, judging parts to be irrelevant when they're actually incredibly relevant. I apologize for saying it, but you really should seek to understand eyesight before you seek to change it. | |

| Sep 18 at 3:10 | comment | added | JBH | I'd like to note that having access to a greater color spectrum in dim light doesn't create a benifit. Quite the opposite. As luminosity dims all colors tend to smear together. That's one of the advantages to having the monocolor rods - high contrast dim light vision. | |
