Pupillary Diameter Meters

Pupillary diameter meters aid eye care professionals in measuring the size of their patients' pupils, which can sometimes be challenging. This information can be helpful to ophthalmologists and optometrists when calculating refractive errors, which can be impacted by a change in pupil size. Additionally, pupils of two different sizes can sometimes be problematic, as can non-circular pupils, so checking pupillary diameters is important.
