I spent a week this month helping my father settle back in to his house after returning from the hospital, and was reminded of some important tips for anyone trying to help organize a senior or someone with limited vision.

• Remember that it's their home, not yours (even if you used to live there), and everything needs to work for them.  The way you might organize your own home is not necessarily what will work for them. 
• Don't move things around without asking them.  My father remembers the locations of gadgets he hasn't used in 30 years, so if someone moves one, whether he needs it or not, he seems to notice, and may spend weeks looking for it where it used to be.  If you have a suggestion for a better place to store it (or donate it), ask first!
• Try to store similar things together whererever possible (all dental and denture supplies on one side of a particular shelf, for example). A tube of hair gel can look like a tube of  denture cream,
  with unpleasant results if they get mixed up.
• Keep any dangerous or poisonous items together in a clearly designated space. 
• Label the shelves to show where things go. They may help your parent remember where things are, but even if they can't read them anymore, labels can help any outside helpers (other family members, home health aides, cleaning services, etc.) put things away in a consistent space.
• Finally, remember that sometimes it's awkward for both you and your parent to have you trying to help them get more organized.  Don't be afraid to get help from a professional if it would make it easier on both of you.
