Notes on Meaning

• The two primary meanings are connected. The original, literal meaning is "partially blind." Over time, this evolved into a metaphorical meaning describing a mental or intellectual blindness—an inability to "see" the truth, implications, or realities of a situation. In modern usage, the figurative sense is more frequently encountered.
