Description
A study of fifty presbyopic subjects was performed to compare the reading addition determined by using the Binocular Cross Cylinder (B.C.C.) method and the Accommodation-Reserve method. Seventy per cent of the subjects accepted a higher addition by +0.25 to +0. 75 D with the Accommodation-Reserve method in which one half of the amplitude of accommodation was kept in reserve. Eighteen per cent accepted +0.25
to +0.75 D less plus with the Accommodation-Reserve method and twelve per cent of the subjects accepted the same add by both methods.
