  Hi Nattycrabbypatty
  
  Hey – thanks for voting for me. Better make sure I come up with a good answer! Losing our sight as we get older is just a sign of the body gradually not working so well. It’s not just our vision, but our hearing and our other senses all slowly begin to fade. The fact is, we didn’t really evolve to live as long as we do now, and we don’t very effectively repair the most high-tech parts of our bodies (like the eye) when we get older. At least for most of us our vision holds up pretty well, and we may never need more than a pair of glasses.
