I can feel and appreciate the difference they make to my eyes and to the quality of my sleep. I would give them a 5 but am somewhat frustrated by the lack of ability to discern colors

These glasses are good. They filter unwanted light frequencies and make you feel like you are at a party in the 1960's.

Everything arrived in a couple of weeks and in a good state.

I've worn them a couple of times now and they are very comfortable but can't use when looking at iphone or ipad as too dark to see properly, Tv just about ok but still a bit dark.
