    Just want to see what members think of the following articles. If Jack Kruse can comment on that will be great. I think we all want his opinions on this study.

    The University of Manchester suggests there’s more going on here than we know. In a blog post about the study, the university noted that the marginal benefits of tinting your phone screen to make it more yellow is outweighed by your eyes’ ability to detect colour. Your eyes respond more to yellow light than blue light In research conducted on mice, the university found that colour-sensing cone cells in the eye may be more responsive to yellow light than the response of melanopsin to blue light. In other words, using your phone in night mode may actually increase the stimuli from your eyes telling your brain it isn’t time for sleep.

    "The research, which was carried out on mice, used specially designed lighting that allowed the team to adjust colour without changing brightness. That showed blue colours produced weaker effects on the mouse body clock than equally bright yellow colours."

    "our perception of colour comes from the retinal cone cells and the new research shows that the blue colour signals they supply reduce the impact on light on the clock."

    "We show the common view that blue light has the strongest effect on the clock is misguided; in fact, the blue colours that are associated with twilight have a weaker effect than white or yellow light of equivalent brightness."

    "Our findings suggest that using dim, cooler, lights in the evening and bright warmer lights in the day may be more beneficial."
