The photograph is an image that shows features.
Use of the aspheric design reduces changes in the face line caused by spectacles to give a natural, beautiful impression.
This is an image of S-6.00D. SEIKO's previous lens used 1.50 monomer.
The two properties of the aspheric curve design that features an aspheric surface on the front surface and the high refractive-index monomer have made it possible to produce an extremely thin lens.
The numerical value that indicates the ability of the lens monomer to refract light is called the "refractive index" and the higher this index, the thinner the lens.
SEIKO has succeeded in achieving a lens that is 48% thinner and 38% lighter than ordinary plastic lenses with its Prestige lens that uses a material with a high refractive index of 1.74, while the standard type Super Sovereign UV is 40% thinner and 40% lighter than ordinary plastic lenses and Super Luscious(S16MX) is 36% thinner and 36% lighter. Benefits of these lenses include alleviation of tiredness caused by the weight of the spectacles, reduced incidence of spectacles sliding down the nose and reduction of traces left by nose pads on the sides of the nose so as to give overall comfort of use.
