I discovered the ladies loved them. I can't remember how many times they paused me to use the reflection to check or do their makeup or hair. Often insisting they be in my lap or straddling me (being tall has some advantages). Even ones I did not know asked for assistance. In at least one instance I was able to cultivate the introduction into a depth check for thickness.
Admittedly, I wore them to be able to ogle females with impunity. I wouldn't be surprised if they made a comeback in the age of metoo#.
Try soaking this in today and you'll wish you had mirrored sunglasses.
