Halo is caused by internal reflection between the back side of the outer lens and the front side of the inner (thermal) lens as light passes through between them. Obviously JT isn't going to apply expensive non-reflecting coatings onto their thermal lenses so you're essentially stuck. Pretty much all double-lens eyewear manifests this effect so you're only choice to rid yourself of halo is a single lens solution - which obviously fogs-up unless you take steps. Best solution I've found is a combination of air circulation (fan) and anti-fog coating/treatment (fog-tech, etc.) but I am an extreme fog-generating machine (don't believe, just look left at my avatar) so even with these precautions, I can't get rid of it entirely.
