Snellen is a Dutch surname.
Snel means "quick" in Dutch and the original bearer of the name may have been a lively person. However, the origin of the surname often was patronymic, as Snel and Snelle were short forms of the archaic Germanic given name Snellaard (which originally meant "lively and strong").
People with this surname include:
Herman Snellen (1834–1908), Dutch ophthalmologist who introduced the Snellen chart to study visual acuity (1862).
He took over directorship of the Netherlands Hospital for Eye Patients (Nederlandsch Gasthuis voor Ooglijders), after Franciscus Donders.
