Reason behind apple watch red flash light

If you've ever tried using the flashlight on your apple watch you may have come across this red screen

Apple's never mentioned why they included it but it does serve a useful purpose and that's what i'll explain right now

When using the flashlight on your phone or even the white flashlight on your apple watch it gives off a pretty bright light that may not be an issue

If you're alone but can be pretty disturbing with other people around for example laying in bed next to someone trying to find something you dropped in a movie theater or just trying to find your way to the bathroom at night

Also when using a bright white light in dark conditions your eyes are forced to transition from night vision to day vision and then back again once you turn the light off

So to address these issues apple added a red flashlight to the apple watch since the color has some unique qualities that make it useful in certain situations, Red light doesn't break your night vision which is helpful for someone working in a dark setting like an astronomer observing the night sky

While using a red light to reference their star charts or a photographer checking their prints in a dark room it's also helpful in the wilderness being less disturbing to wildlife

And even attracting less bugs since they have a harder time seeing red light but if you're someone who's a little less adventurous the red flashlight on your apple watch still comes in handy

If you're in bed at night reading using the red light is much less distracting to the person sleeping next to you if you drop something in a theater the red flashlight won't bother other audience members which is why if your apple watch is in theater mode

The red flashlight will appear by default and if you wake up to use the bathroom at night but don't want to break your night vision or interrupt your sleep as much using the red light to find your way would be much more comfortable and just as a bonus there's also a strobe light mode on the apple watch which is great to use during night runs or early morning walks to increase your visibility for other pedestrians
