Thinking about our senses compared to other animals ours are pretty rubbish. We often develope eye side problems like short-sighted or long-sighted as well which makes us even more disabled. I have never heard of such problems in the natural animal world. Only domesticated get disabled through diseases and lack of care. I guess it is our fault because we bred them like that.
You never hear of wild animals with short-sightedness or long-sightedness, because those that have sufficiently bad sight not to be able to spot predators or prey don't survive—they get eaten, or starve, respectively. It's only domesticated animals and humans, which can get taken care of, which survive with defects. For example, according to Wikipedia domestic cats live 12–14 years, but wild cats have a median age of only 4.7 years (with a range from 0–10).
Make no doubt about it: life in nature is nasty, brutish and short.
