Is it possible or ethical to offer a research option to f.lux? Like you would let the user pick that option and have the software dim the luminosity with or without cutting more specifically blue light then have them report and if they felt any difference after a week/month or a month, repeating the process for a few months/week while either alternating or changing the mode.

Maybe it is a dumb idea as it is too easy to tell whether the software is in full effect or not.
