Which term describes circles of light seen around objects?

Explanation:
Halos describe circular rings of light seen around bright objects, especially in dim conditions. This happens when light is scattered or diffracted by irregularities in the optical media, such as corneal edema or lens opacities like cataracts, creating a secondary ring around the source. Because halos specifically denote those circular light rings, they best fit the description. Terms like monocular or binocular refer to vision in one eye or both, not the appearance of rings, and total blindness means no light perception at all.
