Lens Thickness Comparison	-6.00	+4.00
1.50 Index Our standard lens is single vision 1.5 index Cr 39 plastic resin and is adequate for most people
1.56 Index The tensile strength of this index is lower than any other in general, although some brands have overcome this problem. It is slightly thinner than 1.50 but its lack of strength renders it unusable for Rimless.
1.60 Index Our lowest priced thin lens.
1.67 Index Our mid priced thin lens.
1.74 Index The thinnest plastic lens available as I write.

As you can see demonstrated in the above chart, the saving in lens thickness is most dramatic when used in high minus prescriptions.
