A blindfolded person can't see anything and has their eyes covered.
When we talk about someone being blindfolded, it usually means they have something over their eyes so they can't see what's happening around them. This can be for a game like 'pin the tail on the donkey', or to keep people from cheating when doing a task by themselves. Some people also use a blindfold in meditation to focus on other senses and get more connected with their body.
To cover the eyes, in order to make someone unable to see.
