turned a blind eye

Pretended not noticing

To turn a blind eye is to deliberately ignore something you know is happening, especially wrongdoing: Management turned a blind eye to the harassment for years.

The phrase suggests willful ignorance rather than failure to notice—you see it but choose to act as if you don't.
