A recent Vision Direct study reveals that the average American adult spends about 44 years—roughly two-thirds of their life—in front of screens. As experts in digital wellness, we examine the implications and health consequences backed by data.
This Vision Direct research, reported in the New York Post on June 3, 2020, surveyed 2,000 Americans. It estimates screen time at 6,259 hours per year, totaling 382,652 hours over an average lifespan of 60.7 years. A 2019 Nielsen study found adults over 50 averaging just over 10 hours daily, with those in their fifties and older exceeding 12 hours, while younger adults spend less.
Daily averages include: 5 hours on computers, 4 hours 33 minutes on smartphones, 4 hours 30 minutes on TV, and 3 hours 12 minutes on video games—totaling 17 hours per day. During lockdowns, this rose to 19 hours. While eye-opening, these figures from a 2,000-person sample warrant scrutiny, especially given work demands.
Excessive screen exposure poses real risks. A 2019 British physician linked it to mental health issues. The U.S. National Institutes of Health (NIH) reported in 2018 that prolonged use alters children's brain development. The World Health Organization (WHO) recommends no screens for children under 2.
Blue light is a key concern: studies identify it as an endocrine disruptor harming sleep quality. Spanish research in 2018 flagged it as a risk factor for age-related macular degeneration (AMD), a retinal disease common in those 50–60.
