One in five Americans suffers from dyslexia, according to the U.S. National Institutes of Health. Essentially that means their brains do not process or recognize certain letterforms and symbols. When looking at words, dyslexics tend to rotate, swap, twist, mirror and flop certain characters, making it difficult to comprehend what they are reading. The word “saw” may be read as “was,” for example.
It doesn’t matter how beautiful a typeface is; dyslexics still find them hard to read. In fact, probably the most elegantly fine typefaces are the toughest to make out.
