A Phoropter (or phoroptor) is an instrument commonly used by optometrists and ophthalmologists during an eye examination to measure an individual's refractive error and determine his or her eyeglass prescription. Sometimes a retinoscope or an automated refractor is used to provide initial settings for the phoropter. Phoropters can also measure phorias (natural resting position of the eyes), accommodative amplitudes, accommodative leads/lags, accommodative posture, horizontal and vertical vergences. The major components of the phoropter are the JCC (Jackson Cross-Cylinder) used for astigmatism correction, Risley prisms to measure phorias and vergences, and the (+), (-), and cylinder lenses. Propters are made with either plus or minus cylinders.
