Wild animals generally don't suffer from nearsightedness and the types of age-related vision changes that can plague people, but they do see the world differently, depending on how their eyes have evolved to meet the needs of their species, researchers say. Animals such as whales that live underwater all the time have certain cornea shapes to handle their environment, while penguins have flatter corneas that let them see on land and in water, says veterinarian Chris Murphy, a professor of comparative ophthalmology at the University of California, Davis.
