@Roxxor It helps a tiny fraction of my audience with autism spectrum disorders who feel really uncomfortable with pictures featuring eye contact (check Wikipedia for more sources/info about it).
By putting a CW, it allows them to prepare themselves for eye contact before clicking.
I wish a better system existed to metadata upfront a post with 'eye contact' and let each profile set their preferences about it. But without that, the workaround is to use the CW + eye contact keyword.
