I'm gonna order a pair of glasses from eyebuydirect but before I do that I was wondering what would be the thinnest, lightest lenses and just better overall out of 1.57 index, 1.59 polycarbonate and 1.6 index? I would really appreciate the advice.
My prescription
Right eye - Sphere: +1.75, Cylinder: -0.75, Axis: 176
Left eye - Sphere: +2.00, Cylinder: -1.00, Axis: 173
