Staying sleek

When the prescription reaches a range of +/- 4.00D and more, Tokai says its single vision lenses provide optimal options for patients in both unique 1.70 and 1.76 indices, ensuring the best optical and aesthetic outcomes.

By considering the frame fitting and prescription information, the lenses can be crafted in various designs, including aspheric, bi-aspheric and bi-convex, as well as bespoke bi-aspheric lens technology to produce the finest results.

The company notes its Lutina and Lutina photochromic, both offering 100% UV & 94% HEV absorption, are available in 1.76 material, which is an index that can be tinted up to 85% absorption.
