As part of the ageing process, it isn't uncommon for near vision to go. Recently I bought reading glasses because I've been finding it hard to read up close. More recently I replaced my iPad 1 with a mini and as a result of the smaller size, I'm holding it closer. The odd thing is that I'm finding it easier to read close up now. I can make out the pixels now which I couldn't before. Pretty happy actually and just one more thing to love the mini for, albeit a bit off the wall as far as reasons go
