Experimental simulation of simultaneous vision, published in IOVS

A new instrument is presented that allows simulating visual experience under pure simultaneous vision (bifocal correction). The study demonstrates that lower additions (1-2 D) produce larger degradations in visual acuity than higher additions, and that this effect is optical in nature.
