I haven't tried on sun glasses for years so I cannot say whether it makes my facial blindness worse,but,if are looking for a theory,perhaps it is because shades are changing the way the person usually sees things,I mean...the person is used to seeing another with normal daylight shade,but when shades are put on,it changes that,and the person is not recognised?
Kind of like the way the person is not recognised when they change their clothing?
