  • The real problem its in everyday life

In my opinion core root action should be to find health (medical) issues that cause strain and fix it.
It is not possible to search suitable monitor/phone/car/bulb … whole life.

lillo9546 Have you considered vagus nerve dysfunction? Do have a history of trauma or exercise? How is your muscle tension in your psoas? How is your breathing? Do you suffer from forward neck posture/neck tension? Gut issues? Exploring these areas could yield you benefits.

The more I increase my vagal tone through things like singing or cold water exposure, the better my gut is, the more anti-inflammatory my diet and the more regulated my nervous system is the better the eye strain is I think.

    There are lots of intelligent responses in this thread.

    @Zodios , that's exactly what I was referring to in my initial post.

    @moonpie , that's really interesting! I hadn't thought of that.

    Even if the wiki says

    "Problems with human vision

    It seems that in many cases bad tech triggers binocular vision problems.
    It doesn’t matter if you ever had any binocular vision problems or if your vision is perfect. Bad tech (or bad lighting) may interact with binocular vision, either causing additional troubles to people who have underlying problems or causing troubles to people who have perfect vision."

    @karut , good suggestion.

    I don't think I can go to a doctor and ask them to check everything from my hair to my toes.

    What can I do instead? Where should I start? I think it would be better to have a checklist of things to examine and go by exclusion. Thanks!

      You can try orange glasses that block UV and Blue light. Since "White" LEDs are actually blue LEDs with phosphor material in front of them, if you block the fastly blinking blue part you will only see the light created by the phosphorescence which can't flicker as fast due to nature of the material. Ideally there would be optical notch filter glasses that only block the blue from LEDs so the glasses won't look so orange, but the only ones you are likely to find are laser safety glasses.

        int Nice! Could you link some of them?

        What about Pulse Duration Time and Pulse Modulation Depth?

            moonpie

            Yep, I agreed. One of my lamps has 100hz pulsations, but form is sine-wave, similar to incandescent lamp, and feel okay.

            Perhabs, high freq modulations (> 1000hz), irritates the nerves more than low-freq ( remember old samsung s6… s10 which had sine-wave 240hz PWM and did nothing for eyes )

              So we have new OLED smarthphones with a low PWM freq, but good because of a better waveform?
              If so, who does those tests? I see notebookcheck only check the PWM? (Am i correct?)

              Also, how do I know which is the best wave for my eyes?

                simplex Nice! It would be actually good to know which devices have this sine wave. Do notebookcheck show it?

                    lillo9546 Do notebookcheck show it?

                    Nope, they do not measure such items (or not show it). Almost all modern TVs I measured in ship in jan'24, were square-wave PWM. I dont know why in old (safe) devices, engeneers made sine-style PWM and nowadays - dont do that
