METHOD OF MANUFACTURE FILTER FOR CATARACT PSEUDO-EXPERIENCE DEVICE AND CATARACT PSEUDO-EXPERIENCE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a filter for a cataract pseudo-experience with which a normal person can view just as a cataract patient with the corresponding symptom actually views when a normal person uses it. ;SOLUTION: Plural sheets of filters for haze evaluation, brightness evaluation, and color taste evaluation at different evaluation steps are prepared, respectively. And, cataract visual check experiments are carried out by using these evaluation filters overlapped as necessary, and an optical combination of these filters is selected based on the result of this cataract visual check experiments, and a filter for the cataract pseudo-experience is manufactured according to this selected filter.;COPYRIGHT: (C)1999,JPO
