Light-weight eyewear made from PEEK

04-Nov-16

Together with Evonik Industries, Mentor Optical Limited, an eyewear manufacturer based in Hong Kong, successfully developed its new brand model Plasteel using Evonik’s high performance plastic VESTAKEEP® PEEK- as a lightweight and tough optical frame with a unique patented plastic rim lock design. 
The Eyewear weighs just 9 grams whereas traditional frames weigh as much as 23 grams, thereby offering the greatest wear comfortability. The frames’ rim height can be designed to be as low as 1.6mm while the thickness at the temple can be as thin as 0.9mm. The frames are ultra-strong and can sustain a 360 bending test without breakage providing performance & protection against broken eyewear especially in sport activities. With a patented plastic rim lock design, the frames allow prescription lenses to be mounted easily and eliminate damages associated with traditional "push through" method.
