GREAT Glasses

I love my new Nate day and nite glasses. They are very fashionable, super quality and block the blue lite.
I had to work with customers service because I returned the first pair of glasses I purchase because I chose the wrong style frame. Ryan was terrific to work with; very responsive and helpful. Super company!!
