LENSES WITH A LARGER BASE CURVE AND INTERNAL ASPHERICAL AND ATORIC SURFACE

With a highly developed, so-called free-form technology can now produce a thinner and more precise lens with a wider vision field and of an adequate peripheral areas of any material. Modern digital technology enables us production lenses with sophisticated surface. 

The advantages of internal aspheric[1] / astoric single-focal lens:

  • The entire aspheric / astoric design is on the inside, concave side of the lenses. The lens is spherical on the convex side.
  • Aspheric / astoric design is optimized for both "sferno" and cylindrical values. Aspherical / astoric concave surface[2] is optimal in both meridians, spherical and cylindrical diopters. Costing of optimization is customized for each individual lens.
  • Aspheric / astoric design is optimized for all thicknesses and all materials.
  • All peripheral optical tolerances and irregularities are impaired
  • Peripheral optical aberrations (spheres aberration, astigmatism, irregularities) are minimal. The parameters for vertex distance and angle are fixed,
  • A wide range of construction, positive and negative diopters,
  • Center and edge thickness of lenses are being reduced

OKM AsSport lenses provide better optical effects such as aspherical lenses with aspherical outer surface. The outer surface of an aspherical lens can be optimized only "sferno" diopter, but the cylindrical lenses represent 70% of Rx output and in this case the optical effect is compromised.

OKM atoric lenses have on concave side optimal aphsferic in any meridian and therefore provide a broader and cleaaner vision. Internal aspherical lens is thinner in minus values than a comparable external aspheric lens. Aspheric comes more pronounced with strongerl curves.

OKM AsSport lenses offer a unique solution for those who want a lens with better optical effects.
