Do these work over prescription glasses?

Yes. They are designed to clip onto a prescription frame, so you keep your correction and add polarized glare protection. Check that your frame's bridge and lens shape match the clip.

Are the lenses polarized and UV protective?

Yes. The gray lenses are polarized and carry UV protection, so they reduce glare from water, snow and roads while shielding your eyes from UV.

Will they fit my glasses?

Fit depends on your frame's width and bridge shape. Rectangular frames of similar size work best; very rounded or oversized frames may not hold the clip securely.

Can I wear them on their own?

No. This is a clip-on only model with no temples, so it needs a host frame to attach to.

How do they compare with prescription sunglasses?

They cost less and pack smaller than a second prescription pair, but they add weight to your glasses and look less clean. Dedicated sunglasses fit better and are more comfortable for all-day wear.
