...go into Settings > General > Accessibility, and turn on Bold Fonts. It does not bold every single font, but it does make the home screen fonts much easier to read overall.
do each their own. personally, i it was very hard for me to read the icon labels with the standard font size. using the bold feature actually made the font more like the label font of iOS6 and previous (just did a comparison between the two, and the bold iOS7 label font is just slightly larger, but not by much at all).
