Rod outer segments are designed for optimum photon detection.

K N Leibovic1, R Moreno-Diaz.   

Abstract

The proposal that rod outer segment length is optimal with respect to photon absorption and noise control is extended and tested in a number of species. We find good agreement with our optimality criterion in duplex retinae where rods act as detectors of one or a few photons, but not in all rod retinae nor in those which are exposed to significant photic environmental noise.
