Abstract
Transparent structures that refract light and form images are present in all living animals. Due to the evolutionary process, most of the eyes feature a gradient index lens (GRIN), which helps to reduce spherical aberration and improve overall image quality. The overview of various solutions in nature for clear vision is presented and discussed with the emphasis on the optical design. Examples of the octopus eye and the rainbow trout eye are considered and analyzed. The role of the GRIN structure in the lens will be closely examined using optical models with ray-tracing.
