Apart from being "different" due to its color, I can't find any suitable reason to actually acquire or wear this lens. It's purple, but doesn't really block light and lacks the functionality of so many other lenses.

I like this lens a lot during overcast or around sunset. Its a nice color to have because its different and adds a bit more style to your look.

this is a very very pale lens, its nice to look through cos of the contrast but you cant really tell its violet because its so faint. id prefer this if it was darker and had more conntrast.

This is one of the very best lenses for night driving, especially with modern cold blue led headlamps. Love it. Shame there are not more frames using violet or black violet iridium..
