I had blurred vision in one area the size of a basketball. When I looked straight forward the blurred part was at 11 O'clock. I covered each eye separately but the blur/wavy condition was there for both eyes. After about 10 to 15 minutes the distortion got quite larger and moved to my left peripheral . At 15 minutes there was a strobe effect at my left peripheral. it was gone and back to normal after 30-45 minutes.
