I'm getting an odd visual effect in just one eye. Most noticeable when looking at a colored bright light spot like the LED on the front of the TV etc. Instead of the normal round image, I get a much bigger image of the same color, with what is best described as radial lines from the center, in only one quadrant total size about 10 times the image seen in the other eye. The color makes not difference, get the same effect with red, yellow and green. Noticed it first when driving at night, with the tail lights of cars where there are no street lights. Presumably its a well known phenomenon but its a bit hard to google for.
