This black, silky piece of cloth is completely opaque when held up to the light.

When you wear this blindfold, you gain the blindsight ability out to 30 feet (MM 306). Because your eyes are protected, you are also immune to gaze attacks and spells or effects that rely on sight. You cannot use vision in any way while wearing the blindfold.
