Prosopagnosia is also known as face blindness, which means one cannot recognize a person's face. According to the UK's National Health Services (NHS), it often affects people from birth and is usually a problem a person has for most or all of their life. This, according to the health body, can have a severe impact on everyday life.
People with this condition are unable to recognize the faces of family members, partners or friends. They may find it difficult to notice differences in the faces of strangers.
