No, it’s not a metaphor – I am talking about a real magnifying glass. For people with less than perfect eyesight, this simple tool is a lifesaver.
The magnifying glass I am talking about is built into your phone. It’s a little known feature of both iPhones and Android phones, and it’s called the Digital Magnifying Glass. You can find it and turn it on in the accessibility settings.
If you often use your phone as a flashlight to read a menu in a dark restaurant this tool may help. Take it from someone who uses it all the time.
