• Phoropter is a common name for an ophthalmic testing device, also
called a refractor. It is commonly used by eye care professionals
during an eye examination, and contains different lenses used for
refraction of the eye during sight testing, to measure an
individual's refractive error and determine his or her eyeglass
prescription. It also is used to measure the patients' phorias and
ductions, which are characteristics of binocularity.
