High index 1.67 Progressive Lenses work really well for people with strong prescriptions because they drastically reduce the weight and thickness of the lens. Their thinness allows them to work really well with drill-mount frames, or frames that connect the lenses directly to the tempal arms.

Of note is that high index lenses are much more reflective than other lens types. In order to help with this, we include a free anti-reflective coating because we want you to love these lenses as much as we love you. We also throw in a free anti-scratch coating on all of our lenses and these lenses will protect your eyes from UVA and UVB rays.
