They were keeping an eye on me

  Three black dots on saffron yellow cotton worn as an armband was devised in Germany during WWII, to identify blind civilians.
It is still somewhat in use today.
Such identification limits the wearer from any liability caused by an accident. 


I decided to use the symbol to show my extreme displeasure with the football referee.

I has asked for a translation of the word 'Blind'

The translation I received "Eye Blind"
