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.
Lo que necesitamos son lentes que, al mirar lo lejano, todo se vea claro; y, al mirar lo cercano, se enfoquen los objetos cercanos a su campo visual, sin que tengan que pensar en ello.
