What worries me the most is the fact that monitors and phones are outputting light directly to our eyes. Almost everyone, at least in the U.S. has both computers and phones and those devices output light directly to our eyes. Where as, even in 1997 most people weren't spending all of their time looking into light. We were looking at things with reflected light. Somehow I think this direct light into our eyes is impacting our not only our eyes, but our brains negatively.
