Three Kinds of Eye Fatigue
• Internal eye disorders – Accommodation or Convergence problems
• Strain that can be improved by squinting– Glare or Refractive problems
• Non-optimal text– Text size too small or Contrast too low

Take Aways
ClearType subpixel spacing improves readabilityStandards based web pages in IE9 will get this!
Reduce eye fatigue with larger, higher contrast textDo use 12 point, black-on-white text.Don’t use 9 point, grey on grey text.
Choose font personalities that match your contentDo use serif fonts to convey formality and maturityComic sans is only appropriate for cartoonish materials
There are cognitive benefits for good page layout.A well designed page is more likely to be impactful and cause the reader to act on the message.
