I see this as one of two sides. One being medical related experiments to attempt to mitigate issues related to eyestrain and related phenomena, the other being empirical "triggers" of this issue (like dithering/FRC, PWM or other physical properties of LCD panels) that still exist and should still be solved.
Speaking from experience, potentially having something attempting to interfere with normal visual processing when eyes are damaged and working around the issue is probably just "buying time" until you become more sensitive, at which point certain workarounds are moot.
It's important we don't conflate the two when attempting to investigate the technical causes of this issue and in communication with other stakeholders (like in communication with OEMs)
