Materials Lens Material & Coatings We pay careful attention to providing the highest quality product by selecting the ideal lens material, considering optical quality, durability, and safety, leading us to use 100% Optical-Grade Polycarbonate-as well as superior coatings: Anti-Scratch keeps your lenses protected from daily wear and tear. Anti-Reflective reduces glare and allows others to see your eyes instead of their own reflection. Hydrophobic & Oleophobic makes your lenses harder to dirty and easier to clean. Frame Materials To create the greatest Functional Eyewear means to offer frames of the highest quality. For this reason, we utilize 100% Italian Acetate and German Stainless Steel as the core material of our frames. {Some of our frames even utilize Aerospace-Grade Titanium.} Ra Superlative™ Standard 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. FAQs Q: What is the difference between Daylight and Sunset? Do I need both? A: Our daylight lenses are precisely engineered to filter the most disruptive wavelengths of blue light during the day, preserving visual clarity while supporting eye health and hormonal balance. Our sunset lenses are designed for evening wear, blocking 100% of blue light and most green light to support melatonin production, natural sleep cycles, and cellular regeneration. While Daylight Lenses can provide some benefit in the evening, Sunset Lenses have a stronger effect on supporting sleep. Conversely, because Sunset Lenses block more light than necessary during the day, they can reduce visual clarity — making Daylight Lenses the better choice for daytime use. This is why we offer both lens types, each designed for its specific purpose. Q: Will these help me prevent eyestrain? A: Our Daylight lenses (with a subtle yellow tint) are purposefully designed to provide the most advanced protection from blue light emitted by screens and artificial lighting. They help reduce eyestrain, headaches, and fatigue, while also supporting balanced hormonal rhythms throughout the day. For those who spend extended hours in front of digital devices and prioritize maximum blue light protection, Daylight remains the optimal choice. Q: Can I wear them during the night? A: Daylight Lenses can be worn at night. They continue to provide meaningful blue-light protection, supporting relaxation and sleep. Sunset Lenses, however, are specifically engineered for evening use and deliver deeper filtration to optimize rest and circadian balance. Daylight Lenses are designed to filter blue light from screens and artificial lighting during the day but remain suitable in the evening when a lighter tint is preferred. Scenarios where Daylight Lenses may be appropriate at night include: Eating late and wishing to perceive natural colors while reducing blue light exposure. Evening social settings where a brighter appearance is desirable alongside protection. Nighttime driving requiring visual clarity with blue-light reduction. Gradually transitioning to Sunset Lenses. For optimal evening support, Sunset Lenses are recommended, as they maximize circadian regulation, sleep quality, and relaxation. They may also be worn during the day in specific situations, such as: Working under harsh artificial lighting (e.g., hospitals or offices). Exposure to intense sunlight when additional short-wavelength protection is desired. Together, Daylight and Sunset Lenses provide a complete blue-light management system-supporting energized days and restorative nights. Q: What wavelengths do your Daylight lenses block? A: Daylight Lenses have a hard cut-off at approximately 465 nm, with transmission increasing rapidly above that point. Designed for daytime use, they specifically address retinal health. The wavelengths most associated with retinal stress and oxidative damage peak around 430-440 nm and extend on either side. By fully filtering this range, Daylight Lenses reduce blue light exposure by roughly 95%, significantly minimizing unnatural hormonal stimulation from modern blue-enriched lighting.
