Reduce blue light impact on eyes – at least with Night Shift and F.lux

After reading Lifehacker articles about methods for improving sleep for high-stressed desktop warriors, I used F.lux to reduce blue light at night. It is automatically triggered from sunset to sunrise based on your location. This is available on all platforms.

Well, adjusting screen brightness is important too. And ultimately for a good night’s sleep, stop using a device in bed.

Besides a better snooze, there was also research about harmful effects blue light could cause to the eye. And when I got new spectacles recently, blue filters were already a default provision in the new lenses.

Last week, new research further highlighted the possibility of permanent, irreversible damage to the eye – “Blue light from mobile phones and computers can cause irreversible damage to eyes: Scientific Reports study” [link]. The brief advice there was to “avoid looking at cell phones or tablets in the dark, and wear sunglasses that can filter both ultraviolet and blue light.”

Well, with that, all Mac users should now be keen to trigger Night Shift on their devices – on both iOS and macos). Go to Settings/System Preferences > Display & Brightness/Displays > Night Shift:

Night Shift on iOS
ios-NightShift

Night Shift on macos
NightShift-macos

We will review our use of devices and cut down on mindless scrolling, I hope. But younger users, with long years of exposure ahead of them, will demand better solutions from device manufacturers. Notice has been served.
