Use of the double-sided aspheric design reduces changes in the face line caused by some 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 combination of the 2 designs plus the high refractive-index monomer enable the lens to be the thinnest possible.

“3 dioptre curve and 5 diopter curve”

You can choose from three or five types of lens curve to match the frame format.
Matching the lens curve to the frame design makes them even more beautiful and delivers a pleasant comfort of vision.
