simple eye with multiple lenses
simple eye that has two or more lenses. Some marine organisms bear more than one lens; for instance the copeopod Pontella has three. The outer has a parabolic surface, countering the effects of spherical aberration while allowing a sharp image to be formed. Copilla's eyes have two lenses, which move in and out like a telescope [ http://en.wikipedia.org/wiki/Eye#Multiple_lenses ]
