A phoropter is used to manually determine “refraction” – exactly how a lens must be shaped and curved to correct your vision to a normal state, nothing more. Phoropters are subjective however, based on your visual perception and response to your eye doctor's questions. #imageplus #sightwithoutboundaries #optometrist #eyeclinic #Phoropter | ImagePlus Eye Clinic | Facebook
