I'm actually curious if Scharnhorst is either actually blind in one eye due to combat injury or is simply hiding a heterochromia iridum
She covers her magical eye that allows her to snipe.
Or, you know
The battleship was hit twice by 20.3 cm (8 in) shells; the first failed to explode and caused negligible damage, but the second struck the forward rangefinders and destroyed the radar antenna. The aft radar, which possessed only a limited forward arc, was the ship's only remaining radar capability

In that case, Im gong to say she's blind in that eye, if its not completely missing.
