Flowglasses Day & Night Sync Kit 03

Description

<p><h3>OVERVIEW</h3><br /> <p>The Flowglasses 03 Bundle – Álvaro Edition is engineered to control light exposure across the full circadian cycle. Developed in collaboration with professional footballer Álvaro Morata, this bundle includes both Day Sync and Night Sync lenses within the refined 03 frame. Together, they create a structured shift from controlled daytime performance to near-total evening light suppression.</p></p> <p><h3>DAY SYNC – CONTROLLED BLUE LIGHT MANAGEMENT</h3><br /> <p>The Day Sync lens is designed for daytime use in screen-heavy and artificial lighting environments. Laboratory testing confirms 95.04% blue-light absorption with 100% UV absorption in tested ranges. The lens selectively manages stimulating short-wavelength blue light while maintaining sufficient visible transmission for natural alertness and visual clarity. It reduces visual strain without shutting down the biological signals needed during the day.</p></p> <p><h3>NIGHT SYNC – BLUE AND GREEN SUPPRESSION</h3><br /> <p>The Night Sync lens delivers 99.89% blue-light absorption and 100% UV absorption according to laboratory testing. In addition to eliminating blue wavelengths, it strongly suppresses green light, with spectral blocking above 99% extending well beyond 500 nm and remaining extremely high up to approximately 560 nm. This extended suppression of both blue and green light significantly reduces circadian stimulation in the evening.</p></p> <p><h3>PHYSIOLOGICAL DIFFERENCE</h3><br /> <p>Blue light primarily drives alertness during the day. In the evening, both blue and green wavelengths contribute to continued stimulation of intrinsically photosensitive retinal ganglion cells, delaying melatonin release. Day Sync moderates blue exposure while preserving daytime function. Night Sync removes over 99% of blue light and substantially blocks adjacent green wavelengths, creating a low-stimulation visual environment that supports faster wind-down and sleep readiness.</p></p> <p><h3>DESIGN</h3><br /> <p>Both lenses are housed in the 03 frame, sized 51▢25 for a balanced and comfortable fit. The acetate temples provide durability and a premium feel suited for long wear. The 03 silhouette integrates technical precision with a refined lifestyle aesthetic, allowing structured light control without compromising design.</p></p> <p><p><em>Please note: Flowglasses are non-prescription eyewear. The lenses have no vision-correcting strength (0 diopter).</em></p></p>
