APPLICATIONS

Where flexible LC changes the view

Five product categories already shipping with our LC technology, and we’re working on more.

AR

AR Smart Glasses

AR Smart Glasses

AR Smart Glasses

AR glasses let users interact with virtual and real worlds in real time. Our LC lenses tint gradually in response to ambient light, increasing imaging contrast and quality outdoors.

STROBE GLASSES

Strobe Training Eyewear

Strobe eyewear sharpens visual processing for athletes, security, and rehabilitation, improving eye-hand coordination, balance, and reaction time through active brain engagement.

HELMET

Smart Auto-Dimming Helmet

Smart Auto-Dimming Helmet

Smart Auto-Dimming Helmet

Auto-dimming motorcycle helmets that adjust the lens in 0.1 seconds based on light exposure, keeping the field of view clear and natural so riders can focus on the road.

SKI GOGGLE

Ski Goggles

LC-based ski goggles compensate instantly for changing light. No lens swaps, no batteries needed, solar cells and a rechargeable battery do the work for you.

SUNGLASSES

Adaptive Sunglasses

Activate dimming on demand, even while driving, unlike photochromic lenses that rely solely on UV. Driven by a rechargeable battery and powered by a solar cell.

What is “Normally Open” flexible LC operation mode?

What is “Normally Open” flexible LC operation mode?

In Normally Open mode, the flexible LC is transparent when no voltage is applied (Off State). When low voltage is applied (On State), the flexible LC becomes tinted.
