Love the design. Love the benefits. I've been using the Nate Day glasses for a couple weeks now, while working remotely at home on computers and phones... and I gotta say, these glasses make a significant difference in eye strain and vision acuity at the end of my work day. I've also been sleeping better at night... whether or not that's attributable to the glasses is still TBD. But overall, I'm very happy with this purchase.

My eyes just feel so much better and less tired. The color was unusual at first but I quickly adapted to it.

Love them

Glasses NEVER look good on me and I have kind of a smaller head so I was shocked at how well they fit, they are so comfortable, actually look cute, and I really do feel a difference from wearing them! Going to get my fiancé a pair now!

I bought the popp day glasses and they came bent, so they pinch my daughters head. What can we do about this?

The nate day glasses are great.
