Night Shift Mode In macOS Does Not Have A Significant Impact On Reducing Blue Light Levels
Yesterday, Apple had seen fit to release macOS 10.12.4 update that brings a few changes in the firmware. One of the most notable features part of the update was the Night Shift mode that shifts the display hue to a much warmer end of the spectrum. However, the feature may not have the kind of impact on the display which it was developed for. Let's see some more details on the matter.
F.lux Filters Blue Light Level Far Greater Than Apple's Night Shift Mode
A member of the f.lux team suggested in a post why f.lux might be a better option for users compared to Apple's Night Shift mode. While both, the Night Shift mode and f.lux serves the same purpose - reducing the emission of blue light from the display to improve your sleeping cycle, the latter might be the right option. According to Apple:
Studies have shown that exposure to bright blue light in the evening can affect your circadian rhythms and make it harder to fall asleep. Night Shift uses your computer’s clock and geolocation to determine when it’s sunset in your location. It then automatically shifts the colors in your display to the warmer end of the spectrum. In the morning it returns the display to its regular settings.
Basically, the Night Shift mode and f.lux alters the color temperature of your display. Specifically, it lowers the blue light output that potentially disturbs your sleeping cycle. The team member shared some data that depicts why f.lux is a better option for users.
To begin with, f.lux concludes that Night Shift does not greatly reduce the blue light levels. To prove this notion, the color intensity chart shows the level of blue light before a user's typical bedtime.
As can be seen, the blue light is not filtered as much as it does on f.lux. Hence, making f.lux a better option. In the case of f.lux, the blue light is filtered dramatically. Overall, the chart proves that the f.lux's color adjustments have a far more significant impact on the user compared to what Apple's Night Shift has to offer.
The f.lux forum further notes:
Our circadian system is actually not reacting to small changes in “color”. Instead, it is mostly reacting to the “amount” of light. Our eyes are extremely good at distinguishing little shades of color from each other, but this is a different system than the one that drives circadian rhythms.
Do check out the entire f.lux post for an in-depth insight on the whole scenario. As of now, taking into account the light intensity charts, f.lux delivers a better performance in reducing the amount of blue light emitting from a display. Nonetheless, there will probably be more to the story, so be sure to stay tuned in for that.
