Love em
I love them. I have the yellow lenses right now and I find them good to wear on gloomy days to uplift the mood. Now I need to get the red lenses!

Amazing customer service…. The glasses are great too.
My son‘s birthday glasses are perfect for him. He absolutely loves the gift I sent. Says they are comfortable fit, and make him feel better at night.
There was a huge hiccup with delivery and it was handled with such care and grace.
I really appreciate their exceptional customer service

Difference is clearly noticeable!
This is the 3rd pair I have purchased.
The first one went to my secretary who I initially lent it to for her computer eye strain, as she kept borrowing it..
Second one to my daughter who initially thought it was uncool but somehow still uses it. And this pair I shall keep just for myself!
