Zone Design

Stylish Zone Comfort Zone

The two priorities for a customer when choosing a pair of spectacles are
"functionality" and "fashionability."

The world's first "Zone design" addresses these two conflicting elements.
We have succeeded in achieving both "comfortable vision for the wearer (functionality)" and "a stylish appearance (fashionability)"

Image comfort zone

"Comfort zone" that emphasizes comfort for the wearer focuses on astigmatism and power error correction to achieve a sharp, clear field of vision. Every effort has been made to create a design that provides comfortable vision. In addition, elements such as the size and shape of the "comfort zone" can be changed to match the power and astigmatic axis of the customer's lenses to achieve vision with even greater levels of customization and comfort.

Image stylish zone

"Stylish zone" makes use of the latest technology to reduce distortion around the lens periphery. Zone design reduces changes in the face line due to lens distortion to give a natural, beautiful image also making it possible to produce thin lenses. Simultaneous achieving comfortable vision and thin, lightweight lenses that alleviate the sense of awareness of wearing spectacles.

Effect of Zone Design

Natural face line and even greater beauty of the eyes

Ordinary plastic lenses tend to distort the face line.
"A-Zone" reduces distortion to achieve a natural, beautiful image.
