is a precision-engineered blue light filtering eyewear designed for daytime use, blocking the most harmful wavelengths of blue light emitted by screens, LED lighting, and fluorescent bulbs during the hours when artificial light is most disruptive to your hormonal system, eye health, and energy, while preserving full visual clarity, natural color perception, and the sharp focus you need throughout your day.

Most people associate blue light glasses with sleep. But the disruption starts long before sunset. Chronic daytime exposure to the blue light spike centered around 455 nanometers, the dominant wavelength emitted by modern LED and screen technology, creates cumulative oxidative stress on the retina, unnaturally elevates cortisol, suppresses the healthy hormonal rhythms that should power your afternoon, and builds the neurological overstimulation that makes winding down at night so difficult. By the time you put on evening blue light glasses, the damage from a full day of unprotected screen time has already accumulated.

Ra Optics Daylight Lenses have a hard cut-off at approximately 465 nm, specifically targeting the retinal stress zone centered around 430 to 440 nm while preserving the beneficial portions of the visible spectrum that support alertness, mood, and cognitive performance during the day. The result is a lens that reduces blue light exposure by approximately 95% in the most harmful range without darkening your visual field or distorting colors, making it practical to wear all day, every day, without compromising your work, your screen time, or your appearance.

The Clyde frame is named after Clyde Edgar Keeler, a medical geneticist whose foundational work on the genetics of vision and retinitis pigmentosa shaped the modern understanding of how light interacts with the eye. Round shape with a contemporary transparent frame and clear saddle bridge. Medium fit. Crafted from Italian Mazuchelli Acetate, a premium plant-derived material, and German-engineered steel. Designed for both men and women. Preferred by leading photobiologists including Dr. Alexander Wunsch.

Daylight Lenses pair with Sunset Lenses for complete 24-hour circadian light management. See the Clyde Sunset listing in the SOLUDE Wellness Tools collection.
