Oh dear, this really disturbed me. I work with battered women who often have permanent discoloration above and below their eyes, typically greenish-blackish tinged, from repeated assaults to their eyes. Some women look like they have permanent or tatooed black eyes. Docs explain that these assaults to the eyes damage the blood vessels underneath, so the skin isn't nourished properly, hence the color change.

The long term effect of this "technique" could be potentially damaging, I would think.

I had thought you meant that it was an emotionally "painful" experience, not literally painful. Thanks for sharing your experiences, Anne
