Optician Sans

Optician Sans is based on the same visual principles as the LogMAR chart, adjusted to be used as a fully functional display typeface.

The LogMAR Chart is used by ophtalmologist, optometrists and vision scientist to estimate visual acuity. 

Optician Sans was created by ANTI Hamar and typographer Fábio Duarte Martins, and is available as a Free Download from the Optician Sans website.
