Optimal choice for late night screen-time Promotes healthy circadian rhythm Highest degree of sleep protection Our Twilight™ lenses are designed to provide maximum spectral protection during the final hours of the day. With 26% visible-light transmission, the deep red lenses filter over 99% of blue-violet light across 380–500 nm, including over 99% at 450 nm. Twilight combines deep red lens filtration with a multi-layer metal-oxide coating for our strongest level of artificial-light protection. The lens tint substantially reduces short-wavelength light, while the coating is designed to selectively reflect targeted wavelengths across approximately 400–550 nm - minimising the amount of blue and green light that reaches your eyes after dark. The deep red tint makes Twilight ideal for evening routines and the period before sleep, when minimising exposure to short-wavelength artificial light is the priority. Paired with a clear frame, Lumina Twilight™ combine a light, modern aesthetic with serious biological purpose. Figures based on laboratory spectral analysis. Not suitable for driving.
