Why do so many people need glasses? Like how did we manage for millennia without them? Ok I get we all look at small letters and images on screens and paper these days.

Is it because we are meant to be looking at things from a distance rather than nearby so our eyes haven’t caught up? #ExplainLikeIm5, #BreakItDown, #SimpleAnswers, Shorts, Interesting, Questions
