Your mileage may vary, but as someone with retinal degeneration it makes a pretty big difference. Photons in the red wavelengths of light carry less energy and put a lot less stress on the retina. Screens are pretty unpleasant for me to use unless they have a color filter on them, and it's the same reason I always keep deep red sunglasses on.

I'm not an expert, but somehow I doubt the strain your eyes feel is directly caused by the energy of a photon.

  Retinal degeneration patients are all advised to avoid blue light exposure for this reason. Not only is there a great deal of research to back it up, but subjectively blue light also makes the photopsias and afterimages worse.

    Can you link a source? I've found a lot of sites claiming blue light is bad, without a real reason. This[1] site seems to support my uncertainty.

    Also re: photopsias, and strain. > The wavelength of light may also affect the photophobia percept. Main et al. (103) found that shorter wavelength (blue) light was more uncomfortable for subjects with migraine than for those with tension-type headache or controls. These investigators also reported that longer wavelength (red) light was also less comfortable for subjects with migraine (103).

  Yea downvote me for asking... y'all need to learn to ask.

    You said said that even though you were probably uniformed (not an expert) you thought that somebody with firsthand experience was probably wrong. So technically you learn to need learn (how) to ask. I'm guessing you wanted to ask something along the lines of: "I would not have thought that. Could you point me to some sources that shaped that line of thinking?"
