| Oct 8, 2014 at 8:26 | comment | added | Odihase | This answer is great and seems feasible. Thank you!!! So in a nutshell: The effect of light refraction in different media is only a problem for beings with very convex corneas an flat lenses. Does this mean that e.g. Penguins have a sharp sight inside and outside of the water because of their ability to bend their lenses much more than humans could do. Thus, making their visual system far superior. Or are there some disadvantages with a flat cornea-design? | |
