Researchers found that spending an additional hour per day (past the first) watching screens was associated with a 21 percent increase in the odds of someone developing nearsightedness.The study analyzed data from 45 different studies involving more than 335,000 participants to find a complex relationship between screen time and nearsightedness risk. The analysis collected data from various digital devices such as smartphones, tablets, gaming consoles, computers, and television sets, which were collectively referred to as digital devices.
