Now Blind People can read words through braille – transmitted directly to their retina by researchers
For the first time ever researchers have streamed braille patterns directly into a blind patient's retina, allowing them to “see” objects, colors and movement, read four-letter words accurately and quickly with an ocular neuroprosthetic device in their environment. Ordinarily, this is done with the help of a video-camera-equipped pair of glasses worn by the user, a portable processor to translate the signal from the camera into electrical stimulation, and a microchip with electrodes. In a recent experiment, however, researchers bypassed the camera, transmitting visual braille patterns directly to a blind test subject's retina.
Here's how the Argus II normally works. The prosthesis itself is implanted in a blind user's eye, placing an array of 60 electrodes against the surface of the retina. The accompanying video glasses take in the view in front of the user, and convert the video signal into electrical pulses. These pulses are wirelessly transmitted to the implanted electrodes, which respond by selectively stimulating retinal nerve cells.

I didn't understand what you mean. There are many definitions of what Project Blue Beam is :-).
