I am getting a pair of aviator style prescription sunglasses

They have high impact polycarbonate-No index listed or high index 1.67

Um, for use, high impact would be advantageous for me

However, my prescription sph is -4.75 and -5.50 with axis 3 and 172 and I usually buy high index lenses.

How thick do you think it would it be to get the impact-resistant ones I want the high impact polycarbonate but

I'm worried it will be unwarably thick.

If it's gonna be unwearably thick, then I will go with high index.

I know on larger lenses it makes the outside edge thicker so thickness is even more of a problem on aviator style.

Thank you foe your help
