In between my annual retina check ups, I visit my also stellar optometrist at least once or twice a year, because my vision changes so quickly. In fact it's gotten worse since you started reading this post.
The bad news is my eyes are unusually sensitive, not to mention piercing: like looking into a deep, brown, knowing ocean and seeing answers to questions you've always been too fearful to ask, yet knowing the essence of your soul has been seen and reflected back at you.
Where was I? Oh yeah. What I'm saying is even a one degree change in my prescription, and it's new glasses all around.
My favorite part of the exam is the phoropter. It's the refraction measuring machine in the picture up on top that, when placed in front of your eyes, makes you look like you're going to a masquerade party. Or you're a borg.While you have it on, the doctor keeps changing out lenses and asking "which is better, one or two?" Changes them again. "Better yet?" And again. "How about now?"
I think it'd be great if there were also a phoropter for other life decisions. Spouses, homes, cars, kids, dogs. Something that would give you a picture of what you're getting, and the chance to make it even better.
Of course, not everyone answers the "which is better?" question the right way. Sometimes it's hard to see the difference no matter how long you stare at it. But by then it's too late, your choice has been made.
Which is also the exact moment you realize hindsight is 20/20.
