Do these fit over my prescription glasses?

They clip onto the front of most standard frames, but fit depends on the shape and size of your glasses. Wide or thick frames may not hold the clip securely.

Are the lenses really polarized?

The lenses are described as polarized, which cuts glare from reflective surfaces like roads and water. That matters most for driving and outdoor sports.

Do they block UV rays?

Yes, the lenses carry UV400 protection, which blocks UVA and UVB rays. That is the same rating used on most good sunglasses.

The pack gives you spares to keep in the car, a bag or at home, or to share with a partner. One person rarely needs all five at once.

Can I wear them without prescription glasses?

They are designed to clip over prescription frames, so they have no arms or temples of their own. Wearing them alone is not practical.

Are they good for driving?

Polarized lenses cut glare from the road and dashboard, which helps in bright conditions. Check that your car's displays stay readable, since polarization can darken some screens.
