It's certainly plausible. A more detailed response would require specific scholarship of the interactions between polarized light of this frequency and the cells (or larger scale structures/modes) of the human body, and whether or not there really is a preferential polarized light of this frequency emitted by our devices. Both of those topics are pretty esoteric (well, at least the first one).
If there is such a deleterious interaction, then blocking it is certainly feasible. Whether or not their tech can accomplish that is another deep dive.
