Design Philosophy
The KT-578AU balances soft geometry with subtle definition. Its gently squared silhouette combines a restrained brow with rounded lower lines, creating a shape that feels contemporary yet timeless. Fine titanium construction keeps the frame visually light and composed.

Craftsmanship & Features
At its core is KIO YAMATO’s Ju-Shi hinge, engineered with a synthetic resin washer to create smooth, controlled movement while reducing friction. Tested through more than 30,000 cycles, the system is designed for enduring performance and consistent comfort. Lightweight titanium and adjustable nose pads complete the balanced fit.

Designed For
Those who appreciate quiet design, precise engineering, and comfort refined through thoughtful details.
