Fig. 2

The through-focus modulation transfer function curves of the studied models were measured at three discrete spatial frequencies of 25, 50, and 100 lp/mm. The dotted lines show the values of each lens separately; the solid lines refer to the average of two samples. Overall Vivity demonstrated an EDoF effect beginning 25 lp/mm while PureSee contained a secondary peak at −1.75D. PureSee gained a plateau in its peak position at 50 lp/mm. By 100 lp/mm, both models had a secondary peak again.
