How can I correct the blue/orange halo effect, resembling chromatic aberration, in my photographs like the one discussed in this conversation?

Photoshop has a setting to adjust this under Lens correction
Duplicate the layer
To duplicate the background layer, right-click on it and choose “Duplicate Layer.”
Convert to Smart Object (optional):
Right-click on the layer that has been duplicated and select “Convert to Smart Object.” (for non destructive editing which is my preferred method).
Go to Filter>Lens Correction
Navigate to the Custom tab in the Lens Correction box.
The Fix Red/Cyan Fringe and Fix Blue/Yellow Fringe can be adjusted using the sliders found in the Chromatic Aberration section. Sliders should be moved to reduce the orange and blue fringes.
Finally, adjust the Hue/Saturation
Remove any remaining fringes, Image>Adjustments>Hue/Saturation
Choose the fringe colour, which is typically red or blue, and lessen the saturation
