Ultra Thin (1.67 High Index)
Ultra thin lenses are the thinnest and lightest lenses available on the optical market! With an index of 1.67, these are the most cosmetically appealing lenses and are recommended for those with prescriptions of -12.00 to +4.00. For optimum results, add an ultraviolet protective coating.

As Thin as possible
These are one of our high index lenses with a refractive index of 1.74. High index lenses can reduce the thickness of the lenses of high powered prescriptions. At the same time, they make the lenses lighter and more comfortable to wear, eliminating the "bug-eye" look of conventional lenses. These (1.74 index) lenses are recommended for prescriptions of : SPHERE (+/- 9.25 above) and CYLINDER (+/- 4.25 to +/- 6.00)
