Next-generation double-sided aspheric lens
“Hi-ResTech,” which is the technology for clear vision design, has been upgraded to a double-sided aspheric lens. It has evolved into a high-performance lens through which you can enjoy a clearer, more natural, and more comfortable field of vision.
Double-sided aspheric”optimal” design integrating the optical technology
A natural field of vision with extremely few distortion and blurring is realized by Tokai Optical’s unique double-sided aspheric design.
1.Dedicated front-surface aspheric design for double-sided design
The adoption of the dedicated aspheric design contributes to realizing both improved optical characteristics and a low base curve.
Surface curve setting by type
2.Omni-directional aspherical design for optimal back surface
Made-to-order aspherical design optimized to the power, curve, thickness, and size of the lens after an order is received. An ideal aspherical design best suited for each customer will be applied to the back surface of the lens.
power
Optimum and high performance is realized by eliminating variations in optical performance by powers.
cylinder powe
Omni-directional aberration corrections are made to astigmatism powers. Clearer and wider fields of visions are thereby realized.
size
(Plus power, mixed power)
Aspherical design is created for each lens considering its size. Thus, the lens will demonstrate optimal optical performance with the shape after cutting.
Expanding the clear field of vision
HR-W maximizes natural vision by a design which controls light to concentrate at the fovea centralis.
Clear and comfortable to the surrounding area of the lens
HR-W takes in consideration binocular vision and maximizes the clearness by compensating aberrations following how you will see with both eyes.
A special option desing for near vision
You can choose according to the distance you want to see by purpose-specific distance design.
Near-vision design type (Design exclusively for eyeglasses for very near vision)
You can select a near-vision design type exclusively for very near vision, which is best suitable for office work, smartphone operation, reading, etc.
A beautiful form of the entire eyeglasses is created.
Four types are available for
“Front curve select”.
Optimum matching between the frame curve and the lens
General aspheric lens
The frame curve and the lens curve do not match, and the lens protrudes outward.
HR-W (5curves)
The lens is fitted neatly into the frame because the lens curve is shaped to the frame curve.
Design for each HR-W type
Sophisticated original design.
HR-W comes in two types
and meets customer needs.
Focusing on vision (Clearly)
Higher clearness than Bi-AS (C). Clear and natural field of vision.
Focusing on thinness (Shapely)
Highest index in the world*1 Incredible thinness realized by combination with 1.76.

– we can offer lenses best suited for them with a wide variety of options.
HR can help you find joy in everything you do and see.
Individual [design options]
i Location Remix
The wrap angle, the pantoscopic angle, and the vertex distance are different among individuals, and the three-dimensional positional relationship (i Location) between the eyes and the lenses, which can be obtained by measuring them, is optimized by reflecting it in the design.
