The other useful vision accessibility setting is "Color Filters" - I've used this one two different ways.<p>Currently, I've got it set to put a reddish-orange cast on the screen - like a "turbo night shift" more similar to the depth F.lux will let you take your mac. You can use the Shortcuts app to create a shortcut to enable the filter, and then set that to turn on at certain points, so around 10 at night my phone goes from normal night shift to a much more aggressive red/orange-shifted profile. The effect at night is dramatic - the phone becomes much less jarring to look at. The OLED screens are great for this, too - a reduction in blue color is a reduction in blue light. The shortcut turns itself back off at 6am.<p>The other filter you can apply is a black & white filter, which removes all color from the screen. Give this a try for an hour and then turn it off - you'll be amazed at the riot of attention-grabbing color app makers are throwing at you. I've found it's a lot easier not to get sucked into the phone hole when the UI is set to black & white - the whole device feels calmer and less urgent.<p>If you haven't spent time in the accessibility settings, though, go exploring. It's where Apple puts all the good stuff.
