It is possible to cause eye strain and headaches.

As can watching a HD/UHD TV, please stop scare mongering, I watched a CRT for decades and it did not cause me eye strain and/or headaches any more than my modern UHD TV!!!!!

'Possible', conceivably, in a few cases not 'going to' as you originally posted. Scaremongering is right.

To be fair there is evidence that PWM flickering can cause headaches/eye strain for small number of people. Some UHD TVs (low end models) flicker the backlight at 120Hz. Better TVs flicker at a higher rate making it less of a problem or not at all. 

This is about laptop screens but the same PWM flickering is used on many budget TVs:
