My mom has a ton of trouble seeing close up. I've looked for a magnifying glass to help (her preference). Problem is, I can't find one that is 4X or 5X. You can find them that are 2X with a tiny window that is 5X, but that's not good for her. Question is, where can I go order/buy a 3, 4, or 5 X magnifying glass that is three or so inches wide? Any help with a place to order, or someone to contact with this question would be appreciated.
