"Consider what will most likely happen in the fall, when Apple introduces n ew operating systems. The company says iPhones that can handle that update will be able to operate in ?dark mode.? That should cut bac k on emissions of light and, perhaps, ease eye strain.
I?d like to use dark mode but I can?t, unless I reach for m y wallet. That?s because my iPhone 6, and older iPhones, won? ?t be compatible with iOS 13, the forthcoming version of Apple?s operating system. Owners of older iPads will be in a similar predicament. A nd owners of new Apple Watches but older iPhones won?t be able to u pdate their watches unless they get a newer phone."
