The day I bought new running shoes, Mike and I went for a short hike after lunch. Midway through, I noticed a blurry spot in my vision. A bit later, I noticed that it was crescent-shaped, acting like the afterimage you see when you look at a bright light. It was a very bright day, so I assumed I caught a reflection off a windshield or something. It faded, but it was back the next day. I kept seeing it off and on over the week, and went to my optometrist to get it checked out.
He noticed that my left eye (where I could sometimes see the crescent) was still 20/20 but was now weaker than my right eye, and told me I had vitreous separation, something that happens to everyone when they age. If there's a problem, it will show up within 6 weeks, and I should call if there are changes. He also mentioned that I might need reading glasses.
So I went merrily on, still worrying off and on about the new blurriness. I decided to check in with my g.p. He looked alarmed, suspected I had retinal detachment, and sent me immediately to the ophthalmologist. Several tense hours later, the ophthalmologist confirmed the original diagnosis -- I'm getting old; it's nothing to worry about.
Oh well. I look good in glasses. Time to go buy some.
While I was waiting, I noticed this in the exam room:
If you click through to a higher resolution, you can see it says "Place sharp in container opening then lift door until sharp drops." When did "sharp" become a noun? Why wasn't I informed of this?
