Long hours in front of a computer monitor can wreak havok on your eyes. Give them a break by increasing the font size of the Photoshop User Interface.
In Photosop CS2 you can do so in the General Preferences.
Choose Edit > Preferences > General
The General Prefs dialog box opens.
Select Large from the UI Font Size dropdown menu,
and restart Photoshop.
The font size for the options bar, palettes, and tool tips are all increased. My optic nerves feel better already.
