A true no-bounce

I've worn Goodr, Knockaround, and more - but I like the light feel and no bounce of AER glasses.

The most comfortable glasses ever

I’ve tried them all - ray bans, oakleys, $10 gas station glasses, Goodr … none of them fit me the way I wanted to because of my wonky nose. Enter Alterego and my life has changed because I’ve not felt the urge to break them and throw them away once, I can see, I’ve run with them , drive with them - they live on my face permanently now. Go buy them.
