BAF said: 10/10 is normal, but average is 14/10? Wouldn't that make 14/10 normal? You Europeans make my head hurt. I think they don't mean normal for a person, but a normal baseline after which you need glasses. Makes sense. -- |

I'd think they meant 10/10 was optimal, but 14/10 was the arithmetic mean after you averaged in all the four-eyed people. They all watch too much MSNBC... they get ideas. |

So fighter pilots can "read" something at 14 meters that most people would have to be at most 10 meters away? They all watch too much MSNBC... they get ideas. |

Thanks Neil for reading me correctly. I exactly said fighters pilots. Arthur, I don't really know :-( I know that a 14/10 will have a better acuity than a 7/10 viewer thought ;-p Edit: that one IS what we use there (sized for a 1280x800 screen, reader at 5 meters): "Code is like shit - it only smells if it is not yours" |

I've read of color-blind Spider Monkeys having stem cell injections into their eyes enabeling full-color vision. This is a long shot but do you know if any more more progress has been made in this field toward applying this technique to humans? __________________________________ |

Arthur Kalliokoski said: If you're talking about my flashlight story, yes, the red part was quite a bit brighter than necessary to see it was red. I can't seem to remember to try it again when I wake up groggily in the middle of the night to use the bathroom. Since others here say that it's been known that cones respond slower I'll drop it. It is an interesting phenomenon that I can't reproduce. The thing which doesn't sit well with me is that the cones are in your central vision and the rods in the periphery. And if you can see the colour, you're using your cones for both the tip and handle so I don't see how it would be explained in this manner.

There are also other item numbers which give more or less. Average $ per exam would be about $30. You can do the maths. Note: Consults usually take about 30min.

Although the 20/20 system in on the RHS of the chart. Ben Delacob said: I've read of color-blind Spider Monkeys having stem cell injections into their eyes enabeling full-color vision. This is a long shot but do you know if any more more progress has been made in this field toward applying this technique to humans? I think the experiment gave the spider monkeys the ability to pass a test which requires colour vision. Which is different from having actual real colour vision. e.g. There is actually a contact lens which when worn by colour deficient people that allows them to pass the Ishihara colour vision test. However, you won't get the colour sensations everyone else has. You can just pass the test. This is a good start though but I haven't heard of any trials on humans yet.

Scroll down the page. It's going from 1/10 to 16/10 by 1/10 step. "Code is like shit - it only smells if it is not yours" |

I just assumed baf actually understood what it was he was talking about 
I'll try and not make the same mistake in the future.
