Is there any documented evidence for suicide among vertebrates other than humans? Supposedly Tarsiers will commit suicide when in captivity by banging their heads against a wall. But I think it is difficult to distinguish between "that animal went crazy and lost its sense of self preservation" from "that animal committed suicide". |

Does red light preserve your night vision? Center of sight here is defined as 8 minutes of arc, or about 1/8th of a degree of visual angle. It is a very critical angle, though, since it contains your fixation point. |

Does red light preserve your night vision? You're essentially a dichromat in the center of the eye, so you are blue-yellow color blind there. That means you can distinguish blue from any color, except yellow, over a very small region. You can find a more thorough discussion of the phenomenon by George Wald here |

Does red light preserve your night vision? There are multiple ways that pupils can be dilated, and this one only comes into play with very very bright light. |

Does red light preserve your night vision? -1 here as well, intrinsically sensitive ganglion cells require an outrageously large amount of light to activate them. They are not, at all, relevant to a discussion about night vision. |

Does red light preserve your night vision? It doesn't quite work like this because the chart above shows the relative chromatic sensitivity, which is very different from the luminal sensitivity. That means that you can't compare the height of the Rod curve to that of the L-type cone because they've been normalized to peaks with very different sensitivities. |
