My reading vision has dropped so quickly. You have no idea. In the past two weeks I have noticed a terrible degeneration of my short distance focussing that I have to wear reading glasses ALL the time. ALL the time when I am reading, anyway.
I blame the minuscule font on my Samsung Tab 7.7. It is ridiculous. It is a known issue and quite a few forum discussions. There are a few font-size programs, but they only work for some apps. It's mainly the crappy Facebook app. It doesn't allow the two-finger stretch zooming.
