Determining the beam frequency & EM-component that is emitted from the human eye (supposedly)
that our eyes emit a beam that can be detected


Humbug, bogus and nonsense.  

It's been proven in numerous tests that you can't feel that a person is looking at you. It's easy: person A is with her back to person B. On a time cue they both have to press a button, person A whether she feels B is looking at her, person B whether she's looking at A at that moment. We have the following situations:

1) 0 0 : Not feeling, not looking
2) 0 1 : Not feeling, looking
3) 1 0 : Feeling, not looking
4) 1 1 : Feeling, looking


If this obstinate claim were true 4) should have a much higher occurrence than 3). Which it doesn't. In none of the tests the deviation from 50/50 was statistically relevant.  

Baloney, tosh, bunk.

(10 minutes later)
I watched the video. Tip: watch it first with the sound off, so you won't be distracted by snake-oil talk. Watch it later with sound. Without sound it struck me that Ross (is he really a doctor?) spends 2 minutes of this 5 minute video playing with some wires. That's called impression management, but in fact it's irrelevant. Then he puts in his earplugs and puts on his goggles. Then bends his forefinger a couple of times. And that, my dear man, was the demo. That was all!. He's doing something on his laptop (which we're not allowed to see), and that's probably in the impression management realm as well.  

I'm sure Randi's million is going to be safe for a long while still.  

(I often wonder who of those psychics are just frauds, and who actually believe their own story. Both of them exist)
