Effects of blue light on eye health

people are exposed to blue light via everyday technology, Blue light exposure has been shown to impact health. Some studies also suggest that chronic blue light exposure may represent a risk for the development of age-related macular degeneration and other pathologies. Animal studies have shown that age-related macular degeneration can be induced by blue-light exposure. One epidemiological study has also shown a positive correlation between sunlight exposure – a natural source of blue light- and increased risk of early age-related macular changes in humans. However, this particular association of effects from blue light is difficult to assess in humans and warrants further study.

Iris changes the color temperature of your display. Natural light is more blue, while most artificial light (including candlelight) is warmer. Incandescent bulbs, which we’re all used to, become more red in tone when you dim them. But newer LEDs and CFLs don’t – this includes the backlight on your monitor. If you’re a photographer, you’ve probably dealt with this, since pictures taken inside at night are always much more brown than photos outside. Iris also changes your display brightness in innovative way without PWM flickering. Iris Mini on the other hand is free.

      With SunsetScreen, all you have to do is click “More options…” and check the box that says “Disable day mode”

        Please discard my last message; you just need to put the value “0” without the quotes in the “Delay until sunset” box

    I find auto blue-light filters like flux mess up my gamma calibration even during the day, even when i turn them off (at night, I don’t mind). Any solutions.
