I stepped out to look at the moon...it was high up by then, so bright that it hurt my eyes, and even had two elliptical halos...must have been my bionic eyes giving me an extra treat. I had cataracts removed when I was 60 years old....early in life. I could tell as the other patients were in their 80's. Mine matured early as I had so much prednisone to help me thru several asthma/allergy/lung problems in my 50's. But that is my best guess for the elliptical halos.
