For glasses with screws – Trivex

Light organic lens with HMC additions.
Due to its excellent strength it can be only 1.2 mm thick in the center of the lens and is thinner than polycarbonate at negative diopter values. Minimum thickness at the screw is only 1.2 mm, which means that even diopter lens can be extremelly thin.

Trivex is currently the only lens that combines the characteristics of Polycarbonate and CR39.
Its strength makes it very suitable for frames with screws or nylon. There are no internal tensions in the lens, so it does not break when drilling a hole in it. Compared to polycarbonates, Trivex is resistant to solvents.

Lenses are made of original PPG® material.
The latest variant also with Transitions Signature VII. Quicker clearing of the lens from darkened state.
Very suitable for night driving.

NXT and NXT Polar

The basis of every polarized NXT lens is Trivex® material.
This is a state-of-the-art polymer derived from technology that was originally developed for military airplanes.
Surprisingly light Trivex® material provides a complete balance of visual and physical qualities and enables unbelievable durability and protection, along with high optical clarity.
NXT® is simply the best material for demanding sun lenses.


Light Translation Technology®   

Every NXT® lens is made with Light Translation Technology, a combination of revolutionary material and light reflection technology that satisfies even the most demanding customers.
NXT® lenses are the only lenses that improve clarity and detail of the image in all light conditions, and are also highly resistant to impacts.



Every NXT® lens is designed to let through the light from a particular part of the spectrum and optimizes the reflection within the entire spectrum.
NXT® lenses allow for much more than simple cosmetic corrections, as they filter light at different wavelengths, thus improving the viewing by controling contrast, colours and image clarity.
