Lexend is a collection of seven font families intended to improve reading proficiency. As prescription eyeglasses achieve proficiency for persons with short-sightedness, Lexend's families were developed using Shaver-Troup Formulations.
All the Lexend fonts has been upgraded to variable fonts with a weight axis (from Thin to Black) in June 2021, thanks to the efforts of Font Bureau.
