“…The blue light emitted from LED light sources and screens was found to have an intense spike at a wavelength of 455 nm (Figure d) . Accordingly, wearing spectacles or contact lenses that show maximum protection at 455 nm may assist people, especially children, in avoiding complications resulting from blue light exposure.…”

Constant exposure to blue light emanating from screens, lamps, digital devices, or other artificial sources at night can suppress melatonin secretion, potentially compromising both sleep quality and overall health. Daytime exposure to elevated levels of blue light can also lead to permanent damage to the eyes. Here, we have developed blue light protective plasmonic contact lenses (PCLs) to mitigate blue light exposure. Crafted from poly(hydroxyethyl methacrylate) (pHEMA) and infused with silver nanoparticles, these contact lenses serve as a protective barrier to filter blue light. Leveraging the plasmonic properties of silver nanoparticles, the lenses effectively filtered out the undesirable blue light (400–510 nm), demonstrating substantial protection (22–71%) while maintaining high transparency (80–96%) for the desirable light (511–780 nm). The maximum protection level reaches a peak of 79% at 455 nm, aligned with the emission peak for the blue light sourced from LEDs in consumer displays. The presence of silver nanoparticles was found to have an insignificant impact on the water content of the developed contact lenses. The lenses maintained high water retention levels within the range of 50–70 wt %, comparable to commercial contact lenses. The optical performance of the developed lenses remains unaffected in both artificial tears and contact lens storage solution over a month with no detected leakage of the nanoparticles. Additionally, the MTT assay confirmed that the lenses were biocompatible and noncytotoxic, maintaining cell viability at over 85% after 24 h of incubation. These lenses could be a potential solution to protect against the most intense wavelengths emitted by consumer displays and offer a remedy to counteract the deleterious effects of prolonged blue light exposure.

“…As new artificial light sources are developed, it is pertinent to understand how different light characteristics impact the human eye. The blue component of the emission spectra of LEDs has been of particular concern given the high photon energy of blue light and the widespread application of LEDs in digital device displays [ 13 , 30 , 31 ].…”

“…While there are researchers and associations [ 12 , 22 , 24 , 25 , 31 , 57 ] that are of the opinion that chronic exposure to blue light emitted from digital displays is unlikely to have any long-term impact on the retina, other research groups remain concerned. Blue LEDs have been found to reduce cell viability and increase reactive oxygen species production in photoreceptor and retinal pigment epithelium cells [ 58 , 59 , 60 , 61 , 62 ].…”

With the expansion of the markets about near‐eye display devices and other similar consumer devices, the security of display devices has also received more and more attention. So in this paper, a novel low blue light backlight unit for eye‐protective liquid crystal display is reported. The low blue light characteristic is achieved by a LED with long wavelength (>457nm) chip and K2SiF6:Mn4+phosphors or Red/Green phosphors. The screen with this backlight unit can realize 86% NTSC color gamut with a slight decrease in brightness, 8% or so. In addition, the ratio of toxic blue light region (wavelength ranges from 415nm to 450nm) to the whole blue light region (wavelength ranges from 400nm to 500nm) is less than 40%. Especially, the ratio can be less than 15% if using the chip with longer wavelength (>460nm) and Red/Green phosphors. The screen also reaches the TÜV Rheinland low blue light display certification standard.
