Plenty of people use their iPhones to constantly read emails and text messages – it’s part of the main attraction of the device. But it can get a bit tiring on the eyes.
The iOS software actually has a way for you to increase the size of the text on the screen so that you aren’t straining your eyes all the time.
To do this, open the Settings app, then click on the “general” tab, and then on “accessibility”.
Down the screen, you’ll see an option that says “large text”. Click on that, and you’ll be able to choose which size you want your text to appear.
