I would think that it is an illusion, your eye has problems in the difference in light levels, so an area that is between two bright areas, can appear to be darker than it is, just think how on a bright summers day, any part that is in shadow in your vision, appears darker than it is.

I think, maybe one of the medico's could give you a fuller explanation

I was interested in this as well Mark , its no illution as you say , the only thing i could find at the moment was this

The ring that appears around the moon arises from light passing through six-sided ice crystals high in the atmosphere. These ice crystals refract, or bend, light in the same manner that a camera lens bends light. The ring has a diameter of 22° , and sometimes, if you are lucky, it is also possible to detect a second ring, 44° diameter. Thin high cirrus clouds lofting at 20,000 feet or more contain tiny ice crystals that originate from the freezing of super cooled water droplets. These crystals behave like jewels refracting and reflecting in different directions.
