Skin and HEV Light



  • Hi,

    I am unsure if this is the right section, but it did not seem to belong in any of the others either.

    Studies have indicated that High-Energy Visible light (aka near-UV light) can induce uneven pigmentation (esp. in darker skin types) and photo-aging etc. They seemed to focus mostly on violet/blue band with wavelengths from 400-500 nanometers. As such, sunscreens providing protection against this have surfaced.

    Now to my point: as f.lux reduces/removes blue light when the sun goes down, is it fair to infer that this would accordingly benefit skin (i.e. removing the need for HEV light protection at those times)?

    Also, is anything known about the effect of the rest of the visible spectrum (500+ nm) on skin?



  • Computer monitors are far too dim to be of any risk, even if they produce HEV. Compare the brightness of a monitor to the extreme brightness of the sun. It's almost literally like the difference between night and day.



  • My dermatologist disagrees, at least for those predisposed to hyperpigmentation/melasma etc.
