Have a strong correction but looking good in specs


Nikon, who introduced the first ultra-high index lens in 2000, is a pioneer in creating thin lenses.

For those of us requiring a strong prescription, the benefits of thinner lenses are not limited to how the lenses look in the frame.

They are also beneficial for:

  • Keeping your eyes from looking too small (for minus power prescriptions) or too large (for plus power prescriptions) behind your eyeglasses
  • Improving the quality of vision at the periphery by reducing the curvature of the lenses
  • Avoiding fatigue or frames slipping on the nose because of excessive weight

What makes lenses thin and light is the combination of lens material and optical design.

Lens material of higher refractive index directly results in thinner lenses. Nikon is renowned for being the first brand to launch ultra-high index lenses, with a refractive index of 1.74. Nikon offers a wide range of indexes covering all correction needs.

Thickness can be further reduced by using aspherical optical designs. Nikon is using its expertise in optics to offer aspherical designs that result in the combination of great vision and great looks

Nikon Lite DAS double aspheric lenses feature aspheric optical designs on both sides of the lens in addition to high index material, resulting in improved optics and better appearance:

The double aspheric technology of Nikon Lite DAS gives an outstanding optical performance – unwanted astigmatism is reduced compared to a conventional aspheric design.
