The first thing I do in the mornings is look at my phone. That's mainly because my phone is my alarm clock, but once my eyes are open and that screen is lit up in my hands, it's an awfully short trip to check emails and pursue headlines. There's no reason for me to doing this. My emails that early in the morning are mainly junk, and the headlines won't change much before I' ve brushed my teeth and poured a cup of coffee, right?

My wife says I'm addicted to my phone, I disagree, but I can definitely stand to spend less time looking at it. I'm not terribly active on social media, but I do enjoy me some idle scrolling. And, wow, do these tech companies know how to keep those thumbs constantly swiping up? We've got a daughter. and while I think we're pretty good about limiting her screen time, it would seem that technology has fascinated me from the start. So, I decided to try loosening my phone's grasp on my attention by switching the screen to black and white.

Changing the display to black and white is very easy.  In your iPhone's settings(设置) , choose General(通用功能) , then Accessibility(辅助功能).  Next choose Display Accommodations(显示调节) , then Color Filters(滤镜).  Tap the toggle(切换器)  on and a list of filters appears.

Choose Grayscale and you're all set.
