Judy is seeing blue!

  

Really.  She goes out to walk the dogs, comes back, and says the dogs have blue spots on them; like if you crinkled up blue cellophane and shined light through it onto the dogs and made spots.  How’s that for a mystery?  Wandering blue dots on (mostly) white dogs.

 

Want to think about possible explanations for a minute?  We’ve found the cause, but you don’t need to go straight there.  You can make up your own explanation first.

The blue spots come and go.  We took photographs of the dogs as Judy was seeing the spots and of course, the dogs weren’t actually blue in the photographs.

The fact that the spots wandered around made us think of “floaters”; those black dots that are not directly on your line-of-sight, and if you shift your gaze to try to look right at them, they stay just out of reach.

Judy called the optometrist.  Turns out sometimes when cataracts are developing, they suppress the yellow input which makes the incoming light look blue, but just in spots!  We already knew Judy had cataracts developing (don’t we all), so this is no big deal at all.  In the meantime, Judy can enjoy the blue spots, and when we get around to it, we’ll get cataract surgery on the schedule.
