What we need are glasses that, when you're looking far, far objects are sharp, and when you look near, near objects come into focus in your field of view, without you having to think about it.
Precisamos de óculos que, ao olharmos pra longe, os objetos fiquem nítidos, e ao olharmos pra perto, os objetos próximos entrem em foco no nosso campo de visão, sem que precisemos pensar nisso.
