Visio DS - This back-surface is the value of the future -

There are people who do not use progressive lenses even though they are over 40 and find it difficult to see at near distances. Our firm has focused our attention on the two reasons why these people do not use progressive lenses: (1) They are not used to adjusting the line of vision and so they are difficult to use, and (2) they are concerned about distorted vision.
‘Seiko Visio DS’ are lenses that are easy to become used to and easy to use even for those using progressive lenses for the first time, because they greatly widen the far distance field of vision.
Moreover, “Back-surface + Back-surface Aspheric Design” is employed which reduces distortions in appearance by allotting the progressive surface to the back-surface of the lenses.

Seiko Visio RA and Seiko Visio DW, an intermediate distance lens for indoor use and a very-close distance lens for use at hand, respectively, have been added to the Seiko Visio Series, which also includes Seiko Visio DS, a progressive/very-close distance lens. The availability of progressive, intermediate distance and very-close distance lenses in a single series broadens the range of lens options for different applications, which is useful in a variety of situations.

Visio series features

Lens appearance

Thin, lightweight and comfortable to wear

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

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

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. Visio DS features a lineup of 3 types of material: Ultra-high 1.74 refractive index material, high index 1.67 material and 1.60 index material. In addition, back surface aspheric design is used to achieve a thin lens. The synergy between material and design of Visio DS 1.74 in particular enables a lens that is thinner and lighter than previous lenses.
