The 'Airframe' series: Lightweight eyewear that changed the common belief that glasses are heavy

Since its launch in 2009, the 'Airframe' series has pioneered the 'lightweight eyewear' market and remains a long-selling JINS product supported by many customers. By being the first in the industry to use lightweight resin materials, these frames overturned the conventional wisdom that 'glasses are heavy.' The series has surpassed 26 million units*1 in cumulative sales, ranking No. 1*2 in Japan. It has created the lightweight eyewear market and transformed people's lives.

From 'lightness' to 'comfort' that fits daily life: 3 evolutions of 'Airframe Slim'

The 'Airframe' series has been repeatedly updated in pursuit of lightness. The newly renewed 'Airframe Slim' goes beyond mere lightness, aiming to be eyewear that fits more closely into the customer's daily life, evolving in both comfort and design.

Focusing on the tendency for weight to shift toward the front when prescription lenses are inserted, the new model adopts 'tungsten,' a high-density rare metal, for the temple ends. By intentionally designing the center of gravity toward the rear, it reduces the front-heavy tilt that occurs with lenses, achieving a well-balanced and comfortable fit. Furthermore, the ear-hook section has been updated to a new specification that does not use rubber materials. By eliminating the transition between different materials, a seamless and sophisticated design has been achieved. Additionally, for the first time in eyewear, 'Rilsan(R) Clear G140 Rnew(R) A,' which is lightweight, highly flexible, and heat-adjustable, is used for the front and temples. With more areas adjustable by heat (heater) than previous models, it is now possible to achieve a more precise fit tailored to each individual's bone structure than ever before.

[What is Tungsten?]

A metal characterized by having the second-highest hardness after diamond and a density approximately 2.5 times that of iron. By adopting it as a component for glasses, it plays the role of balancing the weight of the front when lenses are inserted, achieving an optimal center of gravity without compromising the beauty of the minimalist design.
