The manual phoropter may be used to verify the glasses or contact lens Rx. The near vision correction (e.g., for "bifocal" or near reading) is verified by slightly converging (crossing) the two eyes during the exam. Generally the patient does not look down through the phoropter.
A phoropter is a device used in eye exams to determine the right prescription for correcting refractive errors like myopia, hyperopia, and astigmatism. It contains various lenses that the optometrist can adjust to find the patient's optimal vision.
Eye doctors usually use a retinoscope, a direct ophthalmoscope, an indirect ophthalmoscope, a slitlamp, a phoropter, a projector, and a keratometer. This is just the basic list, but there are many more possibilities.

The machine used to measure the refractive error of your eyes and determine your prescription is called a phoropter. During an eye exam, it helps the eye care professional assess how well you see with different lenses. Additionally, the autorefractor is another machine that can provide an automatic measurement of your refractive error.
