Good I like using them. I feel like they are helping keep my eyes safe.
The glasses work wonders. I wear them all day at work even when I am not sitting at the computer. They help with the glare off the lights as well as computer. I wear them watching tv and when I look at my phone. I have an undiagnosed problem with my eyes at the moment and the glasses have help me get through the past month with the annoyance.
Overall, was a skeptic. I work a job that requires lots of screen time, and I figured I would try these out. Definitely not mad at them at all! Highly recommend, in fact I have been recommending to people I work with. I have several pairs of their sunnies, and these lived up to what I expect.
