Optics of the harbor porpoise eye in water.

Abstract

A two-dimensional ray-tracing model for the harbor porpoise eye is constructed from new measurements, mainly on two enucleated eyes, and from data found in the literature. Model calculations show that the crystalline lens has too much refractive power to focus light on the retina. The cornea has a high refractive index and acts as a diverging lens of… (More)
