The effects of screens on children are even worse than you can imagine: they can literally break down the human body. In her forthcoming book, The Tech Exit: A Practical Guide to Freeing Kids and Teens from Smartphones, Clare Morell tells the story of an optometrist who discovered that an eight-year-old girl seeking relief from pain in her eyes no longer had Meibomian glands—which means her eyes cannot produce lubricating tears. Hours of daily digital screen time had trained the child to stare, which dried up her glands. At such a tender age she runs the risk of eventual blindness, as do thousands of other pediatric patients with her diagnosis. It is a fitting illustration of the tragic phenomenon that technology is having on human beings: pained children with blank stares who are unable to cry tears.
In a discussion with James Poulos, Morell explains that well-meaning parents should not simply set up safeguards to filter out the toxic effects of addictive technology. This is like advising a drug addict to use only less frequently, even though every dose is toxic, mind-altering, and possibly laced with a deadly synthetic.
