15102 - Beren's Pinhole Test

The Beren's Pinhole Test combines two test in one, a standard pinhole and a eye dominance test. The pinhole test helps to differentiate between two types of blurred vision. A patient's blurred vision might be caused by a focusing problem, which can be corrected by glasses or contacts, or it may be caused by a disease. A properly conducted pinhole test will pinpoint the source of the problem. The eye dominance test determines the tendency to prefer visual input from one eye to the other. The Beren's Pinhole Test is very versatile because it can be used by hand or placed in a standard 8 Well Flipper, Opto Clip or Trial Frame.
