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 the inability to see anything, even light. If youâre partially blind, you have limited vision. For example, you may have blurry vision or the inability to distinguish the shapes of objects. Complete blindness means that you canât see at all and are in total darkness. Legal blindness refers to vision thatâs highly compromised. What a person with healthy eyes can see from 200 feet away a legally blind person can see only from 20 feet away.
