Or, if you was going to that much trouble, remove the lenses from the glasses. No photoshop needed then ![Smile [:)]](/emoticons/emotion-1.gif)
I've read that the non-reflective lenses are great, photographers live them. I have them but I'm never in front of the camera, always behind!
I haven't tried, but also read, that you should have the sitter facing away from the camera slightly. That way the flash and reflections aren't bouncing back into the camera. Obviously if you are using an off camera flash then don't put this at such an angle that the light from this is bounced at an angle towards the camera.
Good luck!
