FAQ
Are the lenses polarized or non-polarized?
Our racquet-sport lenses are not polarized as polarized lenses block horizontal glare - while this is useful for everyday wear, it can have a negative effect on your depth perception on the court. When you need to see the ball clearly to time your swing, a polarized lens will be an impediment. Regardless, all of our lenses are still 100% UVA/B protective.
I want to try these on, where can I do that?
For now we are only selling from our website so that if you need anything we can help you directly 👊 - however, we do free returns for 30 days after buying so that you can try them on at home without committing. Check out our full return policy here.
Do you do prescription in this frame?
We currently do not, as prescription is hard to put into a shield style frame without adding an insert, which would compromise our frame design.
