INTRODUCTION

Polycarbonate (PC), the most impact-resistant of lens materials, has been widely used for safety reasons, especially for childrenΓÇÖs eyewear. Unfortunately, during the traditional injection molding of PC, the internal mechanical stresses remaining in the molding materials causes an unavoidable Birefringence. This Birefringence is responsible for the phenomenon of double refraction, which causes dizziness and eye fatigue. Our Evolution Series uses breakthrough technology to diecast PC lenses without any Birefringence, ensuring our customers never feel uncomfortable.

DOUBLE ASPHERIC

Only a few manufacturers can cast finished lenses with an atoric back surface (different asphericity in each meridian), mainly limited to 1.67 high-index lenses. Our design of tools combined with our patented diecasting process creates a thinnest, lightest & best visual field PC lens, which is until now the only Double Aspheric PC finished lens in the world.

BLU-TECT

With a very special additive added into the PC materials, our die-casted PC lens can largely reduce UV410 and safeguard our eyes from long term exposure of blue light in the new digital world.
