Can't turn a blind eye to this

If you have ever heard the expression, “turn a blind eye to …,” then perhaps you are familiar with its meaning, which several online dictionaries define as deliberately disobeying or ignoring unpopular orders.

The idiom has its roots in a rather humorous incident, if the United Kingdom-based website The Phrase Finder is correct. It attributes the expression to Admiral Horatio Nelson, the British Navy legend who was blind in one eye.
