Humans have a wide range of vision issues, and many require corrective lenses. How does the vision of different individuals in other species vary, and how do they handle having poor vision since corrective lenses are not an option?

Humans have much greater visual acuity than just about any animal except birds.  A lot of our sensory input is through our eyes... But that's not true for all animals. So visual defects don't have as big of an impact on dogs, for instance, because they rely more heavily on other senses.
