late onset epilepsy

I once heard Huberman state, in a podcast, something like: the human visual system "loves" movement and flashing, or changes in the field of vision, or something like that [0].  This seems similar to the statement that Harold Shipman is Britain's "best" serial killer, in that it contains a presumptive and incorrect value judgement.  More neutrally, one might say that the human visual system "pays attention to" movement, flashing, changes in the field of vision.  One doesn't have to be an expert in evolutionary biology to hypothesise that this may be related to threat assessment, and is thus not just distracting, but stressful, under many circumstances.

Why, then, is it permitted to pollute public spaces with all sorts of flashing lights trying to grab people's attention using this mechanism? [1].  Modern screens can be extremely bright, and a bright screen cutting from cut to cut is, among other things, a flashing light.  Everyday actions like buying a train ticket, using a kiosk counter, going thru an airport, sitting on a train or plane or bus, waiting for a train or plane or bus, being near a shopping district, increasingly come with bright flashing lights in people's eyes.  Are these screens even incorporated in architectural lighting plans, or have they managed to creep down the flanks?

This leads to the concept of "late onset epilepsy", which is not real epilepsy, but is the feeling that one might flip out because the flashing screens are so annoying.  The human being who wants some visual peace then has a medicalised-sounding term to throw in, when requesting screens be turned off.  "Those screens are very bright and keep changing -- please could you power them off, as i have late-onset epilepsy".  I have used this, and it has worked, tho perhaps a simple request would have worked just as well.  An alternative term is "bright-changing-screen intolerant", which is more literally true, but even less likely to be taken seriously.

Aside: this is one of those problems that Guernsey simply doesn't seem to suffer from, with fairly limited exceptions
