Nobody knows why? I don't believe that. I can tell you why. Because they keep looking and focusing on their computer monitors, their laptop screens, their tablets, and their phones, and rarely look up. For hours, for weeks, for months, for years. For kids who are still developing, surely this will be an issue. People playing computer games that create effects that their eyes would normally do; blur effects, dust effects, light effects... Prolonged usage is confusing their eyes - Eyes trying to unblur a blurred screen. Eyes trying to look deep into the distance, but in truth they are focusing on a screen 12 inches away... When's the last time these people 'losing distance vision' got outside and looked around?
