Added To Yesterday’s Thoughts On The Vision Of Fish
September 4th, 2005 | No Comments »I failed to add yesterday that to completely understand the vision of any specie one must additionally have morphological measurements of the structures of the eye, (distances, indices of refraction of each element etc.) in order to computer simulate the eye’s light refractive properties. If this data is available this is a relatively straightforward matter using modern optical simulation computer programs (such “Light Tools” from Optical Research Associates, Pasadena, CA). Wavelength determinative factor in the vision process. Individual receptors do not discriminate among wavelengths. Evolution placed, at positions on the retina, three
narrowly-tuned receptor types to be in agreement with the wavlength refracted to that point by the structure of the eye.
