I purchased these after having cateract surgery and the surgeon advised to get sunglasses that protect your eyes from the suns harmful rays

When driving: Need to get used to the way these REALLY knock out harmful sun rays .

Yes, lightweight, fits great , blocks nasty uv rays.

Additionally, they made my bike computer readings not as clear as with other glasses.

Seam sturdy and work as they should

I hope you enjoy them as much as I do if this helps you please indicate so thanks

well they don't squeeze my head as bad as
