For more natural, comfortable use.
We ceaselessly pursued this simple and important goal for progressive addition lenses. Consequently, we succeeded in developing Double-surface progressive addition lenses that maximize the potential of progressive addition lenses. The distinctly beautiful form derived from a new design concept and superior performance of these lenses combine to deliver an unprecedented level of comfort when worn. We are proud to introduce the TOKAI WS-C line of high-specification progressive addition lenses that go beyond what back-surface progressive addition lenses can offer.

(1)Dramatic reduction of swaying feeling and distortions

The incorporation of a newly adopted progressive, aspheric design into the front surface of these lenses has dramatically reduced swaying feelings and distortions. Facilitating natural eye movements, these lenses have been designed to be easy to use.

(2)Expanding the field of vision

The adoption of a light-transmitting aspherical design has helped to combine improved vision with a thin, lightweight profile. A reduction in the amount of lateral blurring associated with progressive lenses complements the broadening of a sharp field of vision.

(3)A wide clear field of vision can be achieved even for those with some astigmatism

An optimal aspheric design can be applied to address a degree of astigmatism in all directions to provide wearers with comfortable vision. These lenses are also recommended for a person who has strong astigmatism and is difficult to get used to conventional progressive lenses.

(4)Optimizing the near-range field of view

Our unique design for near vision area reflecting such individualized data as the characteristics of each eye and the distance to objects improves the binocular near-range field of view at side.

(5)Can be fitted to trendy frames

Select from among three basic designs for which an exceptional balance has been struck for near- to far-range use. Irrespective of your familiarity with progressive lenses, you may also select the latest in small-sized frames.
