Our Lens Technology

Eagle Eyes sunglasses were developed from original NASA optic technology,

created by two JPL scientists: James B. Stephens and Dr. Charles G. Miller. Stephens and Miller were studying the harmful properties of light in space when they came across inspiration here on earth: the eyes of birds of prey.
Eagles and other birds of prey have unique oil droplets in their eyes that help to block intensely radiated light rays, reduce glare, and provide heightened color contrast and definition.


For three years, Stephens and Miller worked with other JPL researchers to create and commercialize a lens technology that mimics the key functions of an eagle's eyes, blocking damaging radiation while enhancing vision. That research became the basis of Eagle Eyes' original blue-light­blocking technology, which astronauts used while working in space. Today, it is the foundation of all our Trilenium® blue-light-blocking sunglasses.

From One Lens Technology, to Four

With over 30 years of dedication to providing vital eyesight protection and enhanced visual clarity, Eagle Eyes has remained at the forefront of eyewear innovation and as the visual needs of the world have evolved, so have our technologies.

Today, our exclusive technologies include solutions for lenses for any time of day and for various lighting and environmental conditions.

Eagle Eyes offers solutions for protecting your vision during the brightest days as well as in low light, digital, and nighttime situations. The development of every one of those technologies has been inspired by the dedication and innovation Stephens and Miller showed in creating their original NASA optic technology.

Lenses for Every Light Condition


Eagle Eyes' polarized sunglasses use our exclusive Trilenium® lens technology to block blue light and 99.9% of harmful solar radiation, while expanding your vision. Exposure to UVA and UVB radiation can contribute to the development of cataracts and damage your retinas. Scattered blue light could increase your risk of macular degeneration. Eagle Eyes' Trilenium® sun lenses block all three types of damaging radiation. radiation.

Low Light

Enhance your ability to distinguish objects in low light situations. Our Stimulight® low light lenses come with micro-infused amber lenses to provide enhanced visual definition and contrast in conditions like dusk, dawn, rainy, hazy or foggy weather.


Our night vision glasses with Night-Lite® technology are designed to filter out high-intensity glare and soften harsh lights from oncoming cars, street-lights and billboards, while enhancing clarity and definition at night. This helps to improve your ability to detect and distinguish objects and fight temporary blindness when driving at night.


Our exclusive DigiTec® lenses are specially formulated to block and filter blue light from e-devices and augment the color contrast between objects. With an anti-reflective coating to reduce glare and cut harsh light, these lenses help to reduce the digital eye strain caused by looking at computer screens and digital devices for long periods of time. View all your digital content clearly, with comfort and protection and without strain.

Testing Eagle Eyes Glasses With a Blue Light Meter

Eagle Eyes' sun lenses protect your eyes by blocking blue light and 99.9% of harmful solar radiation. Watch the following demonstrations to see just how much blue light is blocked using a live blue light meter.

The lens is infused with our revolutionary StimuLight® Lens Technology so you can instantly "switch on the light" to enhance existing light conditions and help improve definition, clarity and contrast during times of ever-changing lighting and environmental conditions. 


Night-Lite® optical technology works to filter out high-intensity glare in night driving situations. It works to soften harsh lights from high beams, lifted trucks and semis in the oncoming lane, along with overly bright LED signage.


DigiTec® computer glasses are designed to fight digital eye strain. They block scattered blue light emissions from computer screens, smartphones, tablets and e-readers. This can help to reduce fatigue, squinting, tired eyes and the other associated symptoms of digital eye strain.
