Why is there a “red” flashlight on the Apple Watch?
The white light flashlight on your iPhone or Apple Watch gives off a pretty bright light.
This light is fine when you are alone, but it can be annoying when there are other people around you.
The white flashlight is too bright to use when you’re sleeping next to you in bed, looking for something you’ve dropped in a movie theater, or looking for a way to the bathroom in the middle of the night. It may cause annoyance.
Also, if you use bright light in a dark place, your eyes will change to receive bright light from night vision.
And when you turn off the light, you are forced to return to night vision.
So Apple has added a red light flashlight to the Apple Watch to address these issues.
Red light does not reduce night vision. Therefore, it is convenient for people who work in dark places.
This means that this red light flashlight has the property of being useful in certain situations.
