Rethinking the Process of Vision
A New Explanation for Light Interaction with the Retina of the Eye and the Vision Process
This BBC video above "Colorful Notions" from 1985 first summarizes the classical theory of color vision and follows with the ideas of Edwin Land who personally explains and demonstrates his experiments. It can be viewed as an introduction to this work.

Diagram of the Basic Light Absorption Process in the Retina
by Gerald Huth on January 10, 2008
A diagram summarizing my explanation for light interaction with retinal receptors. One sees to the left the interaction of light as the wave of classical physics adjacent to the side wall of an individual receptor (either cone or rod). It is the dimensions of this space between individual receptors that geometrically defines the wavelength of the interaction. Absorbed light energy is then transduced, in the direction orthognal to the direction of light incidence, through the bilipid membrane that forms the thylakoid disk structure (there are many of these disks “coin stacked” forming the length of the receptor outer segment). This represents the point where the electromagnetic energy of light (“speed of light”) is converted to phononic (i.e., mass associated , “speed of sound”) energy. I believe that this latter transport mechanism actually involves “coherent phonons” or solitons with this quantized vibration being lossless. The intercalation of cholesterol into the bilipid biological membrane structure implies the existence of solitonic transport. This laterally transduced energy then reaches the rhodopsin complexes contained within the thylakoid disk structure resulting in the isomeric transition of the retinal molecule and generating the electronic signal used in the image-forming process of vision. This complex forms the “quantized electron” space of the light interaction process. The role of the variably dimensioned, retinal-enclosing, opsin protein is as a “spacing element” to fit the signal generating retinal into the wavelength-determining ,variable dimensions of the retinal surface (cone-to-cone, cone-to-rod, etc.). In short, “the retinal molecule is constant with the dimensions of the opsin molecule being variable”. The reason for the lengthy “stack” of individual thylakoid disks that form the outer segment is to encode a directional signal for use in the image forming process probably via a “giant electrical dipole” mechanism as I propose.
