Brief

The article proposes that adjacent cone cells in the fovea function as optical fiber couplers, selectively transmitting different wavelengths of light and providing a new anatomical basis for color vision theories, including a four-stage model and the formation of an erect image in the retina.

Summary

This article proposes that adjacent cone cells in the fovea function as optical fiber couplers due to strong coupling between their outer fibers and inner segments. This theory explains color preprocessing, unifies the trichromatic and opponent theories of color vision, suggests a four-stage model, posits that an erect image forms in the fovea, and explains the absence of S-cones in the central fovea as a mechanism to enhance spatial resolution. The authors' calculations support this new understanding of color vision.
