Interesting research into patents on nervous system control through emissions from screens by a person that worked for DARPA. It’s something to be aware of and have in the back of your mind. And it’s an actual fact that your brain activity changes when you watch television.
One intriguing possibility comes from research conducted by Herbert Krugman in 1969. Krugman—who would go on to become manager of public opinion research at General Electric in the 1970s—was interested to discover what happens physiologically in the brain of a person watching TV. He taped a single electrode to the back of his test subject’s head and ran the wire to a Grass Model 7 Polygraph, which in turn interfaced with a Honeywell 7600 computer and a CAT 400B computer. He turned on the TV and began monitoring the brain waves of his subject. He found through repeated testing that “within about thirty seconds, the brain-waves switched from predominantly beta waves, indicating alert and conscious attention, to predominantly alpha waves, indicating an unfocused, receptive lack of attention: the state of aimless fantasy and daydreaming below the threshold of consciousness.”
Krugman’s initial findings were confirmed by more extensive and accurate testing: TV rapidly induces an alpha-state consciousness in its viewers, putting them in a daydream state that leaves them less actively focused on their activities and more receptive to suggestion. This dream state combines with the nature of the medium itself to create a perfect tool for disengaging the viewers intellectually, removing them from active participation in their environment and substituting real experience with the simulacrum of experience.
In a word, TV hypnotizes its viewers.

Now an interesting wrinkle, newer Apple and Samsung phones are constantly bombarding you with infrared radiation, taking images of your face for the screen unlock and application security. Beyond just long term safety concerns for your eyes, is it having an effect on your central nervous system as related to the patents above? The piece below is a good overview, but the language around conspiracy theories online makes me think it’s to appease advertisers and the phone manufacturers. And someone used a IR camera to pick up the scans that happened every 5-10 seconds from an iPhone.
From what we know right now, we can be pretty sure that Iris Scanner and Face ID won’t hurt your eyes. But nothing’s for certain. Even though modern scientific studies show that low-risk IR products are harmless, nobody’s tested the effects of daily exposure over a span of, say, 30 years.
If you’re concerned that the IR light from your phone is bad for your eyes, then you may as well turn it off. That being said, there’s a very good chance that everything’s okay.
