Yellow Lens Pigment: An Adaptation for Activity in Bright Sunlight

  • Seymour Zigman
Part of the NATO Conference Series book series (NATOCS, volume 7)


Anterior eye light filters are present in many vertebrates which modify the quality and quantity of sunlight radiant energy that reaches the site of vision, the retina. In this way, nature seems to have provided a means to protect the retina from an overabundance of short wavelength visible and long wavelength UV light which could interfere with vision and cause damage to it. Any additional light of 300 to 400 nm reaching to the eye could upset a delicate balance that would be detrimental to vision.
