Blue rings around light

[Anfield]

I am slightly nearsighted (-0.50) and for the last 10 months I have noticed blue rings around certain types of light at night. As I get nearer to the light source the blue ring converges until eventually, when I am near enough, the ring is no longer visible and I the light will then appear normal. I have had a full eye exam and there was nothing of significant pathology to note. I was just wondering if there is any explanation as to the cause of this. I have noticed this phenomena on very bright lights mainly such as floodlights and halogen car lights. Other lights such as normal street lights are generally not a problem.

I see rings around the street lights too.  And around other lights point sources.  It is not right as I was a kid I didn't see them... or at least they were not as big and vivid as now at 78 years of age. I know I have cataracts and am taking drops, Can-C for that.

Thank you, my own theory was rather similar to yours. I had a thorough eye exam and the opthalmologist told me there was nothing wrong with my eyes but he had no idea what could be causing the blue rings. I felt like he was not taking me seriously. I will try glasses and see if this makes a difference.

Ever hear of anyone recover from this? (in case of Macular problems..).   I got AIR and the startbursts are highly annoying (to understate).

This would come from optical abberations in the eye eye. there are many causes: needing glasses, corneal astigmatism regular or irregular, cataracts, corneal scars, macular problems, if you wear glasses they can also cause these abereations

I also see these (even streetlights, and starbursts from headlights of cars)
These are visual halos.   They are normally associated with a number of eye "diseases" (ie. glaucoma, retinopathy and cataracts).   It seems there aren't any good scientific explanations out there.   Occular scattering of light inside the eye would be my choice (the light doesn't "bend" right at the lens and does not get focused on the right part of the retina).   Blue might be the most affected color, as it's on a higher wavelength and scatters more easily.

i have the same problem, would like to know as well.
