e-Tint® is synonymous with cutting-edge visual technology.

e-Tint® is the science behind the world’s most famous high performance, electronically tinting eyewear and visors. Designed for use by the United States military, e-Tint technology is now available in eyewear, goggles and visors for soldiers and civilians who require precision optics every step of the way.

The result of two decades of research, development, and testing by the award-winning physics team in AlphaMicron’s renowned laboratories, e-Tint® brings advanced science to bear on modern eyewear. Leveraging proprietary liquid crystal technology, e-Tint® is the world’s fastest transitional eyewear, bar none. A single e-Tint lens will transform from light to dark, or dark to light, in less than 0.1 second.

e-Tint® is the technology used in preferred eyewear for:

  • United States military personnel
    • CTRL® is the only APEL-approved eyewear
  • Tactical professionals including first-responders and the police
  • Award-winning professional athletes including Tour de France winner Andy Shcleck and Mountain Bike Champion Søren Nissen
  • Extreme sports athletes – skiing, snowboarding, motorcyclists, and more
  • Recreational hunters and outdoorsmen


e-Tint’s unprecedented tint-adjustment capability and speed was designed around the needs of the most discerning users on a global scale: the United States Department of Defense. Created to address and overcome mission-critical conditions, e-Tint has a long history of meeting exceptional performance.

Working with Special Forces and the Army, e-Tint successfully developed the first military-grade liquid crystal technology for sunlight protection in the battlefield, where speed, control, and safety are essential. The eyewear is now the first-ever electronically controlled tint-changing eyewear to be approved and included on the United States Army’s Authorized Protective Eyewear List (APEL). The eyewear is available and approved for use by active soldiers. To serve those who serve our country has been the Company’s highest accomplishment to date.

Now, e-Tint® technology is available to members of the military and to the public. Whether day or night, in any weather condition, wearers have complete control over the tint of their impact-rated eyewear or visors.

No interchangeable lenses.

No lag time.

No settling.

Tint that automatically changes faster than the blink of an eye.


A recognized global leader in liquid crystal photonics, AlphaMicron solves light control problems with a vertically integrated approach that combines scientific mastery with design expertise. From solution concept to ISO compliant testing and production facilities, AlphaMicron continues to innovate and deliver optical devices that feature dynamic light management for a host of industries.

Flexible Functional Films


AlphaMicron scientists were the first to create flexible functional films with a unique, patented liquid crystal layer that can quickly (within 0.1-0.01 seconds) change its tint through application of a low voltage. This film can be laminated to a lens or glass to create an electronic tint-on-demand™ film. The operational characteristics of this unique guest-host LC film can be tuned using different parameters and proprietary formulations.
