Stay Glare Aware

Polarized Lenses

Polarized lenses cut glare by filtering out horizontal light waves, like the ones that bounce off water or the road. Without this glare, you’re left with a more gentle view and reduced eye strain, not to mention crisper, cleaner details!

Good for the money

Glasses fit well and are comfortable with a hat on. They stay on my nose well. I only have two knocks: 1) Depending on the way you look, you get a good amount of sun reflecting on the inside of the lens. 2) i have had them for one week and my daughter knocked them off my head and the lenses scratched. Limited lens durability but i know this was my own fault. Still nice sunglasses for the price point.

My favorite sunnies

These are the best sunglasses I’ve owned, and I’ve owned some expensive ones! They offer excellent sun protection and are very comfortable to wear. They are such a great value for the money-I’m actually on my 3rd pair!

Incredible Customer Service

I had some sunglasses and some coating wore off on one of the lenses and I contacted customer service and they said they would take care of it and I was so happy with how they let me know the plan and I was so happy and had everything resolved. The people in customer service are top notch. They made everything so easy. THANK YOU!!!!
