Talk:Scotopic vision

From Wikipedia, the free encyclopedia

define photopic, mesopic and scotopic vision and give examples of each in everyday occurances.where do the peaks of photopic and ssotopic vision lie in the vissilbe spectrum

[edit] wrong evolution?

I wonder why at scotopic vision, smaller wavelengths are more important for good perception, than in photopic vision. Wouldn't it be more advantageous the other way, as the ambient light at night is far more red than blue? By looking at CIE Illuminant A (night) and C (day) and comparing them with scotopic and photopic vision, one can see that for day it does make sense, but our night vision would be better if the eye wouldn't swich to scotopic but stay with photopic vision. I can not find an explanation for this, it simply does not follow the rules of evolution.--TeakHoken193.187.211.118 (talk) 10:11, 23 January 2008 (UTC)
