Is my iPhone causing my vision to get bad?

I use my iPhone. A LOT. The past week I noticed I'm having trouble reading things far away… I usually always have perfect vision. I mean I can read it but I have to focus. Is there anyway to stop my eyes from getting weak and having to wear glasses? Should I not use my iPhone for a few days? Help! Well also… I use my phone in the dark at times. And finally… I started noticing this about the same time I started fasting from sunrise to sunset… I don't eat or drink anything from sunrise to sunset… Including water. It's for religious purposes. Anyways, could it be because I'm not getting proper nutrition? I also have a headache all day when I'm not eating. But the headache goes away after I eat at night. So is it the fasting that's doing it or am I getting bad eyesight?

The bad vision might have something to do with the fasting, like low blood sugar, being dehydrated, etc, I think, wait until the fasting is over and see if your vision goes back to normal. If your vision was going bad because of genetics, it usually happens so slowly that you scarcely notice.

  • What could be causing my iPhone to not be holding a charge? It's an iPhone 4, and I've had it a few months short of two years. I've taken good care of it, it's got plenty of memory, updated software, I'm not running many apps (I double click the home button to close them often), but my phone's battery won't last at all lately even when I don't use it very often.
  • IPhone sync issues causing frustration? My iPhone won't sync with my PC itunes and does without any problem with Mac which is not mine. Its a 4s I just bought and all the other iPhones do sync without any problem. No matter I select to sync contact with google contacts, outlook contacts are synced. It's also happening on PC.
