Where do I find the triple click for red light on iphone?

To set up a triple click shortcut to change your iPhone screen to red, follow these steps:

1. Open Settings on your iPhone.
2. Go to Accessibility.
3. Select Touch.
4. Scroll down to Back Tap.
5. Choose Triple Tap.
6. Select "Nighthawk" or "Color Filters" option (you may need to create a shortcut for color filters depending on your iOS version).

This feature allows you to adjust your screen to a red hue, which can help reduce exposure to short wavelength light, thereby supporting better sleep and lower cortisol levels, particularly in the evenings. 1
