At Ra, we are committed to creating products which achieve the highest degree of excellence in quality, performance, and impact.



All of our products are developed under the careful direction of Dr. Alexander Wunsch (M.D., Ph.D.), the world’s pre-eminent expert in photobiology and applied phototherapy, {who has over 35+ years of clinical experience with light and light therapy.}



With Dr. Wunsch, we have developed a set of superior, proprietary standards for the quality and efficacy of blue light protection eyewear: the Ra Superlative™ Standard.



These include:


• Wavelength-Specific Blue Light Protection: we utilize wavelength-specific LEDs to test for optimal blue light protection in the primary ranges of biological concern 
• Short- and Long-Term Stress Tests utilizing high-intensity blue and full-spectrum LED light sources directly on the lens to ensure that Ra Lenses can endure extreme conditions beyond any normal exposure—and that their protection will endure for a lifetime.
• Careful Measurements of Color Rendering to ensure optimal color perception, usability, and visual comfort—balancing maximum protection with a superior wearer experience.
• Extremely Calculated Selection of Lens Hue—drawing from Dr. Wunsch’s 35+ years of clinical application of color therapy to select hues which support and enhance our lenses’ desired physiological and psychological effects. 

We are so confident in our products, we guarantee you will love them, feel the benefits, and that they will transform your life.



Powered by the Science of Light (decades of research on light’s tremendous impact on health), developed under the care and guidance of the world’s leading expert, and backed by over 100,000 happy customers, this is more than just a feeling. It’s a fact.
