SEIKO Comfortable Vision Lens | SEIKO Lenses for Myopia, Hyperopia and Astigmatism | Lens

Please note that these products are a description of those available for purchase in the Japanese market.

The core series of lenses for myopia, hyperopia and astigmatism.
SEIKO developed the world's first Double-aspheric lens to minimize distortions and improve peripheral vision right up to the edge of the lens. Improving wearer vision and comfort also resulted in thinner and flatter lenses.

Double-sided Aspheric Design

Emphasizes the beauty of the eyes

*The photograph is an image that shows features.

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

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

The two properties of the double-sided aspheric curve design that features aspheric surfaces on both the front and back surfaces plus 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 material to refract light is called the "refractive index" and the higher this index, the thinner the lens. SEIKO has succeeded in achieving a lens 50% thinner than that of ordinary plastic lenses with its SPG-AZ, a lens that uses a material with a high refractive index of 1.74. Wearers can enjoy the benefits of using the thinnest lens in the world. Being thin also means being lightweight. This lens is 40% lighter than ordinary plastic lenses, solving problems such as spectacles sliding down the nose or traces left by nose pads on the sides of the nose.
