Something of a delayed response from me as I first tried to remember why it seemed a familiar thing, then I tried to figure it out, and then I gave up and several failed searches later found an answer on quora amongst pages and pages on the subject and yes on reading, my response was ffs duh of course it is (etc).
From this I learnt that it was related to some battle between two egyptian gods where one lost an eye and the other lost a testicle, the overall narrative I believe being a sort of merchant's parable to emphasise that the philosophy of 'an eye for an eye' is one of strict exchange, and that one may not simply substitute one type of ball for another.
Why do celebrities cover one eye in their pictures/albums/videos?
