It's probably happened to you. Your reading glasses were left in your car or at home, and you're trying to read a menu in a dimly lit restaurant. So what happens? You give the menu to your spouse so he or she can read it to you. How embarrassing. You are not illiterate, but you may as well be, because you can't see!
For some reason, we never seem to have the same problem with our smart phones. We NEVER forget those!
Now I am not advocating giving up your reading glasses, as reading for prolonged periods with a magnifier can induce eye strain. But these apps are just too cool not to share.
iPhone's app is "iCanSee" which essentially turns your Smart phone into a magnifying glass. The Android version is "Magnificent Magnifier HD" and there are several versions of both available - most are free.
You can adjust the magnification, apply an autofocus feature and yes, even turn on a light to illuminate what you are looking at.
For those of us age 40 and over who wear contact lenses, with or without a multifocal correction, this app can be really helpful in situations where the contact lens reading power is just not strong enough to resolve extremely fine detail or poor lighting.
So now you have a tool in your pocket or purse that can work, in a pinch, to read those stock quotes (not that you really wanted to see those anyway!)
