HOW CAN WE PROTECT OURSELVES FROM BLUE LIGHT (SOLAR AND ARTIFICIAL)?
One idea put forth by Arjmandi et al. is that increasing the distance of the screen or camera flash from oneself can reduce the intensity of the blue light reaching one’s skin.
Secondly, maybe we should be considering changing the peak emission of LED photoflash in cameras as well as LEDs used to power smartphone, tablet and computer screens to different colors within the visible light spectrum, whose exposures have not been shown to cause oxidative stress and skin damage.
Regular sunscreen with UV filters that are meant to protect against UVA and UVB radiation do provide some protection against visible blue light, however it is insufficient. Therefore, sunscreen that contain UV filters as well as physical filters would provide protection against UVR as well as harmful visible light.
In conclusion, there is a growing body of evidence suggesting that both natural blue light emitted from the sun as well as artificial blue light emitted from screens and camera flashes can induce oxidative stress leading to skin damage and accelerate skin aging. Further research is needed to better determine the long-term impact of such exposure.
