You've been working on your iPhone all day using Facebook, writing email, re-working spreadsheets, playing games and creating notes. Your poor eyes are on overdrive and overkill with trying to read all that small sized font. Your eyes need a break before you get a major headache! How can you increase the font size so that you can decrease eye strain?
Simply go to Settings / General / Accessibility / Large Text on your phone and change the font size (when you tap Large Text) to a bigger one. Sizes range from 20 points to 56 points. Doing this will automatically increase the text in your Calendar, Contacts, Mail, Messages and Notes! No more squinting and reading will be so much easier!
