Phoroptor model INS-11010 manual. Provides highly accurate readings over a wide range. Used in measurements of Myopia, Astigmatism, Hyperopia, Presbyopia, Heterophoria, Range of Accommodation, Convergence, Aniseikonia, Stereopsis and Binocular Vision. Rapid, accurate readings on binocular visual balance. Speedy astigmatism tests with interlocking mechanism of the cross cylinder lens axis and the cylinder lens axis control ring. One touch accurate astigmatism readings are now possible. In short, middle and long distance test, it is possible to have the optical axis of the lens and the line of patient vision match.
