Double Blind In the context of a clinical trial, double-blind means that neither the patients nor the researchers know who is getting a placebo and who is getting the treatment. Because patients don't know what they're getting, their belief about what will happen doesn't taint the results.
Blindness is defined as the state of being sightless. A blind individual is unable to see. In a strict sense the word blindness denotes the inability of a person to distinguish darkness from bright light in either eye. The terms blind and blindness have been modified in our society to include a wide range of visual impairment.
