Lens appearance

Emphasizes the beauty of the eyes

  • Previous lens
  • STARVISION aspheric lens

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.

Thin, lightweight and comfortable to wear

  • Previous lens
  • 1.60 lens
  • 1.67 lens
  • 1.74 lens

This is an image of S-6.00D. SEIKO's previous lens used 1.50 monomer.

The two properties of the aspheric curve design, an aspheric surface on the front side and the high refractive-index material, have made it possible to produce an extremely thin lens. The numerical value that indicates the ability of the lens material to refract light is called the "refractive index" and the higher this index, the thinner the lens.
UP 1.74AS, which uses the high refractive index 1.74 material, is 48% thinner and 38% lighter than general plastic lenses. The standard UP 1.67AS and BL 1.67AS are 40% thinner and 40% lighter than general plastic lenses. UP 1.60AS is 36% thinner and 36% lighter than standard plastic lenses.
