Green glare on glasses

In the attached photo taken at a 50-year high school reunion, there is a green glare in the corner of both subject's glasses. The camera is a Canon t3i with a 18-55mm kit lens. Picture stats: f/4.5, 1/100, ISO 400, focal length 29mm. For lighting I used two Octaboxes with bulbs at 5500K. Setup was in the corner of a large hotel ballroom, lit with fluorescent, with custom WB set to fluorescent.

My questions are:
1. Should I have used AWB?
2. Is it possible to correct the green glare in PhotoShop using Color Curves Channels alone, vs. Cloning?
3. How can this be best avoided when shooting in a fluorescent environment? Subjects wanted their glasses on.

Many other subjects with blonde hair had a green tinge to their hair.

I would like to enlarge image for more critical view. Please re-post same image, but check box labeled (store original).

Looks to me you should have gelled your strobes and used an FLD filter on your camera, as your strobes were putting out "daylight", while your WB was set to fluorescent (The FLD filter would have eliminated the green glare and some green gels over your strobes would have blended your strobes with the fluorescent).

Octaboxes were continuous lighting. No strobes were used

The artifacts appear to be a reflection of a circular light source behind camera. Green cast may be a product of protective coatings on client's corrective lenses (glasses). Observing reflections during photography, and slightly tilting heads is the easiest prevention. Now, judicious use of PhotoShop can remove color cast.

You white balance should have been set to 5500k. Then your exposure should have been f5.6 or f8 at 1/100 to eliminate any fluorescent "cast" at your set 400 ISO. Do not use AWB as it'll change with the clothing of each subject couple, and be a nightmare to print. Increase the power of your strobes to get this output. It is your option to charge for retouching glasses reflections out of the image. Most Pros do, either in the cost of their print, or as an "extra", especially since you gave them the option to take the photo without glasses.
