In response to Barb Mallut's request for info: When I check traffic coming from the left at an intersection, I see a double set of cars. To handle this, I close my left eye and with only the right eye can see the traffic okay. No problems in seeing straight ahead nor to the right. My opthalmologist tested the eye muscles last year. He said some of the eight muscles that are in charge of moving the left eyeball were not cooperating probably due to PD. Bob Baker 74/4
