Clinical impact of nanophotonic blue-light filtering spectacles based on fullerene C60 and polymethyl methacrylate (PMMA)

Abstract: Koruga holds a patent for the method of manufacturing an optical filter with fullerene C60.Other authors have no conflict of interest to disclose Clinical Impact of Nanophotonic Blue-Light Filtering Spectacle Lenses based on fullerene C60 and PMMA 3 Abstract Background / Aim. Blue light might be harmful to the retina. The nano-material fullerene C60 and PMMA transforms light into harmonised light and absorbs violet, blue and UV wavelength. The aim was to evaluate subjective or objective impact on daily activit… Show more

“…The lenses of the Zepter International light therapy products under the trademark Bioptron and Hyperlight eyewear products use a coating with carbon nanoparticles of fullerene C 60 , which creates polarised, polychromatic and incoherent (out-of-phase) light with low energy and with no UV radiation [18,19]. These light properties are found to induce bio-stimulative effects on the eyes, beneficial for a range of vision improvements and complementary treatments with standard ophthalmological methods [20]. The application of this coating on eyewear produces less eye strain and symptoms typically associated with eye fatigue, as excess light exposure (particularly blue light) may cause photochemical, photomechanical and photothermal retinal damage, as well as influencing overnight melatonin secretion and circadian rhythms [21,22].…”
