I just wonder what you're doing to get the 85mm f/1.8 to produce so many CAs as it's not a lens which is prone to them at all! Neither is the 50mm f/1.4 so this has to be something which you're doing wrong.
85mm) Lateral chromatic aberrations (color shadows at harsh contrast transitions) are basically a non-issue - this is a very rare characteristic.
50mm) Similar to most other fix-focal lenses chromatic aberrations (color shadows at harsh contrast transitions) are very low and nothing to worry about.
My advice would be to work on your technique it's better to avoid problems than to try to remove them in post processing. The lens hoods for these lenses are not supplied with them, so it might be worth buying them, and try to avoid the worst high light levels and sharp edges.
Then again the more I think about this the less sense it makes! Taking portraits with a lens wide open and you're getting CA's? on the face?? The background should be blurred out so the only sharp contrast possible is in the in focus areas, i.e. on the face. I've never come across anyone getting CA's in this situation I might have suggested a faulty lens, but it's happening with both of them, are you sure that you're identifying this correctly? There are lots of other potential issues when you open a wide aperture lens up.
