Optician Sans Serif Typeface (OTF)
A typeface based on the historical eye charts and optotypes used by opticians worldwide. The LogMAR chart consists of 10 letters and was developed at the National Vision Research Institute of Australia. Optician Sans is based on the same visual principles as the LogMAR chart, adjusted to be used as a fully functional display typeface. Designed by ANTI Hamar and typographer Fábio Duarte Martins.
