Idioms and Phrases

Subject about which one is ignorant or biased. For example, The boss has a blind spot about Henry; he wouldn't fire him for anything , or Dad has a blind spot about opera; he can't see anything good about it . This term uses blind in the sense of “covered or hidden from sight.” It has two literal meanings: an insensitive part of the retina and an area outside one's field of vision. The phrase has largely replaced blind side , which survives mainly in the verb to blindside , meaning “to hit someone on an unguarded side” and “to deal an unexpected blow.” [Mid-1800s]
