The comment may be completely fine, if, for example, it comes from having had a gazillion patients who claimed to have eyestrain and eye drops fixed the problem. If you have proof that eye drops don't work on you, then fine, feel free to correct him and call someone who just tried to help you "ignorant".So are you saying that it is not ignorant to suggest that people who do suffer from the PWM effect, should use eye drops, when that suggestion is based on lack of knowledge, that there really are people who suffer from such a problem?
i.e. in my experience....Now people have been using displays since the eighties at work and at home, but only during the last couple of years LED or AMOLED displays with PWM have spread wide, in correlation with eye drop commercials, whichs were almost nonexistent 10 years ago, at least where I live. If they advertise, people must also use those more.
Eye strain and computers is certainly not a new topic from the 2000s. There is plenty of peer reviewed publications, and, yes, at least a A/B test:

They all conclude that "dry eyes" is the most common cause for eye strain after prolonge computer use. So yes, I can say with plenty of confidence than PWM is not the cause of eye strain for most people, despite "my experience".
Regarding eye strain because of flickering, as said, there are some cases indeed, which I know of because of complains that happened when they forbid classic lightbulbs. In fact it has been proven that on specially sensitive persons lighting flickering at less than ~70Hz can even cause seizures. For example:
