Hi all, I've had problems with screens off and on for a few decades but the last couple of years I've been on a full-on and obsessive mission to find a solution and have looked into PWM and other stuff too since I am also sensitive to non-pwm screens on phones, tablets, laptops, and monitors. My reactions vary with devices and other factors too and include anxiety, tension, headaches, itchy-eyes, sticky-eyes, brain-fog and even the triggering/aggravation of my psoriasis. This forum has helped in my investigations, thanks.
About a week ago I had the idea of trying out limiting my peripipheral vision and tried first using a pair of swimming goggles (which were uncomfortable) under my reading glasses, and then just some masking tape on the sides and top of the glasses. Later I found that I needed the tape only on the sides/arms, about an inch wide near the lenses and tapering towards my ears.
The amazing result was that my symptoms significantly reduced and I could finally use some of the numerous devices I've acquired (mostly second hand) on my mission, like the Surface Go I'm typing this on, which was particularly bad. It takes a bit of getting used to having blinkers on but I seem to be getting more comfortable with them and, surprisingly, also seem to be more tolerant to some screens even with them off. I'm still (excitedly!) checking this out and would like to hear about the experience of other screen-sensitive peeps with this approach. All the best!
