1.76 index “The World’s Thinnest Lens!”

‘The world’s thinnest lens’ from Tokai is a pioneering innovation in high precision optics, opening the door to an unprecedented union of couture frame design and optical performance.

The 1.76 index is the result of dedicated research by experts with an established history in their field. This latest advance from Tokai has been tirelessly extended and refined to produce an enviable range of single vision and progressive lenses.

Developed with the discerning customer in mind, this revolutionary material means bespoke frames can be partnered with the very thinnest lens – even sleek, rimless mounts. Flexibility is key to this index, with a range of 80% ABS tints and transitions VII availability. It’s perfect for higher prescriptions where patients are much more sensitive to the thickness and optical performance of their lenses. The 1.76 index perfectly combines these two aspects to ensure the ultimate in aesthetics and lens design.

There’s no doubt the 1.76 is at the pinnacle of high precision optical technology, complementing all contemporary frame innovations, and ensuring bespoke eyewear never need compromise on style.

The key benefits of this index are:

  • Full range of single vision and progressive designs (including SV stock 1.76 AS)
  • Tintable up to 80% ABS (the tint is consistent throughout the lens)
  • Transitions VII availability in single vision and progressive designs
  • Suitable for rimless mounts
  • High base availability (SV = 3-7 base), (progressive = 4-6 base)
  • Larger natural visual field guaranteed by advanced aspheric design technology
  • 99% transparency
  • Full UV400 protection
  • Super Power Shield (SPS) super hydrophobic thin film coating
  • Tokai Blue Coating – blue light filter coating
  • At Tokai UK, we aim to exceed customer expectation, bringing the ultimate optical performance to the market place while celebrating the very best in aesthetics.
