Answers:
I would say 1!.67!. It will come with anti-reflection and scratch resistant coatings as standard so will look nice as there will be no visible reflections on the lens!.
It's not just refractive index of the lens affects the thickness, the size of the frame will affect the edge thickness!. The smaller the frame the thinner the edges!. The distance between your eyes will also affect the thickness!. You should chose a frame where your eyes are in the centre of the lens, this way the thickness will be equal on both sides!.
A good optical adviser will be able to select a frame that both suits your face but your prescription too!. Sometimes it is not necessary to go for the thinnest lenses, just selecting a good fitting frame will do!.Www@Answer-Health@Com

1!.67 should not be thick in that frame!.
It's not just the 1!.67 index lenses though, the lens must be made as thin as possible by the lab!. Polished edges might look good with this frame along with a high quality anti-reflection coating!.
