A lot of women that I've come across rarely make the association between their smartphone use and their headaches, eyestrain and fatigue issues.
They've always put it down to other female health related factors.
Two distant female family members and one close female friend were all experiencing similar issues with headaches and fatigue - and they were all using amoled/oled devices.
I made the correlation and explained the issue maybe attributed to their devices. I lent them some of my LCD phones to use temporarily - and literally the effects were miraculous - almost over night - their symptoms disappeared.
They have not all totally refrained from using their amoled phones, because the camera's produce higher quality photos and videos, however for general web browsing, youtube & netflix etc - they use pwm free phones that I've recommended, when they're at home.
They've also shared this information with their own friends - and from the feedback I've received - the issue seems to be a lot wider spread than we realize, and it's affecting many women just as much as men.
