A nearpoint card was designed for detecting changes in astigmatism at near. The procedure involves vertical prism for partial dissociation of the nearpoint target and the JCC lens for testing of the astigmatic axis and power. 40 P.U.C.O. students were selected for participation in this study. The study compares the experimental procedure to the commonly used distance monocular JCC procedure. Results show the experimental card to most often provide equal or improved near visual acuity as compared to the distance JCC results.
