[1] on her follow-up assessment a newly single woman with great distance vision but poor near vision... "I don't have to pull our my reading glasses to decide which way to swipe on Tinder!" and [2] a very very nearsighted man recently reports wearing his new [extended wear] contact lenses to bed let's him see his partner better.
