If a pair of glasses makes you "four eyes," then two pairs must make you "six eyes."
Soon after the first of the year, I got a second pair of glasses for computer use and reading. Ahhhh, another of the joys of mid-40's. In addition to seeing my computer screen, iPhone, books, magazines and other documents much better, I discovered a surprise bonus. My reading glasses are a creativity booster, as they help me to focus (literally) on only those things that are closer than three to four feet away.
What helps you focus and concentrate?
