I Wore Blue Light-Blocking Glasses for a Week and Here's What Happened

Wearing them at my computer all day, it was a little tough to discern just how much of a difference the glasses were making — especially as I know myself to be particularly vulnerable to the placebo effect. (What can I say? I'm gullible.) That said, when I wore them while using my phone, the effects were much more noticeable. When I'm reading a book or playing games on my phone, my eyes usually start to feel a little strained and tired after half an hour or so. With the glasses, I didn't experience that feeling of eye strain, even though I got sucked into reading a page-turner ("Lethal White," the latest from J.K. Rowling's alter ego, Robert Galbraith) for well over an hour.
