Does this have any similarly with staring at a fire?

  Oooh, good question! Anyone able to answer this?

    Certainly a fire produces light in this wavelength, but also in many other wavelengths nearby, so since a narrow band seems to be the requirement for the eyesight improvement, it's probably not optimal.
