RNIB's free Tiresias font makes text easier to read for the partially sighted

In Greek mythology, Tiresias was a blind prophet. The Tiresias typeface (above) has been designed for British charity, the Royal National Institute of Blind People (RNIB). Tiresias was originally distributed to allow blind and partially sighted people better access to information through a well-designed typeface that's easy to read and can be machine-read. This goal yielded a typeface that works beautifully at both large and surprisingly small sizes.

Tiresias is a sans serif font, and includes all upper and lowercase, numbers, punctuation, mathematical symbols, some diacritics, and special characters. Tiresias is a nice alternative to Comic Sans if you're looking for a typeface that's very easy to read, although Tiresias uses a stacked letterpress lowercase a (but a regular lowercase g).

Tiresias is available in five different versions with slight variations. All come with regular, bold, and oblique faces. Tiresias LPfont includes very tiny curves on the edges of all glyphs (regular and oblique) which gives it a stylish upper hand; and its relatively narrow glyphs add to its distinguished nature.
