Justizia is blind folded, but she can see in darkness.
The idea that Justice can see in the dark comes from ancient Greek mythology regarding Themis (the original Greek counterpart to the Roman Justizia).
Because Themis was a primordial Titaness of divine order and prophecy, she was never originally depicted with a blindfold. Classical poets and mythologists—most notably Hesiod in his Theogony (c. 700 BC) and later Greek dramatists—emphasized her supernatural sight.
As a divine oracle who knew secrets unknown even to Zeus, it was understood that her vision transcended physical light. Her eyes were open because divine justice must see all hidden truths, effectively allowing her to "see through the darkness" of human deceit, secrets, and illusions.
The blindfold itself was actually not an ancient concept; it was added much later by European artists during the Renaissance (around the 1500s) to represent the modern ideal of impartial, "blind" justice.
