mydriatic
Makes pupils widen
Mydriatic describes something that causes the pupil of the eye to dilate.
The term appears almost exclusively in medical contexts—mydriatic drops are used during eye exams to widen the pupil for better viewing of the retina.
As a noun, a mydriatic is any substance that produces this effect: The ophthalmologist administered a mydriatic before the examination.
