don't give him your phone then.
and don't let him look at stuff within arm's reach during daytime either. eyes develop proportional to daylight and gazing into the distance. the eye balls grow in length to just the right length that daylight focuses on the retina is in focus.
if you fail at this, he'll need glasses, and if you fail hard enough, not even glasses will fix this.
bad eyesight is preventable. it's on you to prevent it.
if eye doctors or anyone else tell you that staring at things within arm's reach all day doesn't harm the eyes permanently over time, sucker punch them. they're full of shit retards.
even adults can recover some of the damage of near-sightedness with exercise. go outside, find something that's far away, more than 100 yards. focus on it for a few seconds. then go cross-eyed or focus on something really close, less han half a foot away. hold for a few seconds. then relax and focus on that spot in the distance again. repeat a couple times. do that several times a day.
