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 MyopSee 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:
- Thickness of MyopSee is reduced by about a third compared to standard lenses, and can be up to 16% thinner compared to conventional, single aspheric lenses.
- The double aspheric technology of MyopSee gives an outstanding optical performance – unwanted astigmatism is reduced compared to a conventional aspheric design.
