Another parameter to headaches & eye strain - 5G Networks

Not sure it matters in your case, but try to replace lamp into 2800k spectrum, it doesnt have big blue-peak

Regarding 5G - it can be. Our DDR5 memory works in similar freqs, so there could be interferencies which makes extra voltage pulsations between components

Check to see if any applications you use have any type of "auto detect connection speed" setting linked to any sort of video/image display quality setting.

For example, YouTube's default resolution for playing videos will change based on your connection speed. On my gig Ethernet, it defaults to 1080p for most videos, which causes me eye strain. I need to manually set it to 480p to make the video comfortable to watch. Lots of games do this as well.

So maybe the upgrade from 2G to 5G caused an app you use to see that huge increase in connectivity and bandwidth and it increased some display quality setting to a higher resolution or color depth automatically and that could have caused your issue. Reverting to 2G limited your bandwidth to what it was before and would have reduced the video settings back to previous and no longer cause issues.

ensete hey this is my work laptop - Macbook Pro M1 2021 model. I use extensively for coding and web browsing (Mostly texts and images and not videos).

My network is fiber broadband connection. Wifi Router is Tp-Link with wifi network of 2.4Ghz & 5Ghz. Router is configured to have 2 separate wifi ids. Speed from 2.4Ghz connection itself 40-50 Mbps more than enough for my work requriements. 5Ghz connection speed is in the range of 150-200 Mbps which thankfully I don't need it for the time being.

moonpie You've spent 1 year looking at dithering and PWM. The only thing 5G could have done is allowed you to have more screen time (gaming, high resolution video, higher frame rates, etc) due to faster internet.

The impact of 5G cellular and/or 5GHz WiFi on eye strain has been ruled out? What is your source?

macsforme the source is something he came up with in his head, just like other ridiculous claims he has made lol. RF certainly negatively affects our body. Anyone claiming it doesn't is a laugh.

macsforme My cellular network is 4G LTE and I have not yet upgraded to 5G networks.

This issue which I mentioned in the post is from broadband wifi router's 5G connection to Apple macbook pro or iphone 15 phone

Summary - somehow 5G signals may interfere with your good setup and make it worse. Please post if you also encountering similar issues with 5G.

Yes, Extremely High Frequency (EHF or mmWave) signals can impact the human body.

For anyone that doesn't believe this to be the case, take a look at this book:
The Invisible Rainbow: A History of Electricity and Life. Arthur Firstenberg

As for your eyestrain concerns, it's really hard to pinpoint anything specific to a individual as their solution, as there are a multitude of external and internal factors at play.

Since you're from India, you could even be having eyestrain issues from air pollution.
All one can do is trial & error, sadly...

hey my symptom is not eyestrain or headache or pain in the eyes. Symptoms are neck and shoulder pain. Difficult to focus the screen.

Just rule out its in my mind related, I asked my wife to connect network discreetly then I tried to use the laptop. Whenever laptop is connected with 5G wifi network, I immediately got the symptoms. If laptop connected to 2.4G wifi network, everything normal. So this is definitely not my mind related.

Anyhow I am not going to scratch my head on this anymore. I will continue to use 2.4G wifi, avoid 5G altogether and carry on with my work and life.

If you are not having these issues, then you are good and blessed with good genes maybe. But don't undermine my sufferings. its real and not fake.

Just shared this post to know if I am alone or anybody else also have this issue.

moonpie I will try changing the router and update the status in sometime.

jordan

karthi3219 hes being a dick. RF does effect people negatively. Id ignore that guy. https://pubmed.ncbi.nlm.nih.gov/29069439/

This is about 2.45ghz so could only imagine how much worse 5ghz is

moonpie yeah 2020 is when it got bad for me where I couldn't use screens. Your point? Anything else you want to creep on and dig up from the past?

Why are you here when you consistently cause conflict on this forum with users? You're behavior is so abnormal. You got some issues or just love attention that you get with your stupid comments. Weird

karthi3219 Hi!

Sorry to read you are in pain and wish I'll be able to help somehow.

From my experience, any wireless frequencies emitted with enough energy might interfere with your body over an extended length of time. Contrary to the popular belief, it doesn't have to be ionizing to be harmful. The difference is, ionizing is most likely harmful over a very short period of time, where as non-ionizing is most likely harmful over a very long period of time (often longer than the length of the studies claiming the opposite). And "harmful" doesn't necessarily mean "cancer". The list of health effects is pretty exhaustive. Also, not everybody is affected the same way. It very often depends on your lifestyle and if you were blessed with good genetics or not.

That being said, I tried to help somebody else on this forum. Here is the link to my post if you are interested to read, down below. The only sensible way to be able identify your problem is to measure it. Unless you are actually taking measures, it's just guess work, which won't help you solve anything efficiently.

There you go. Feel free to ask questions if you need more clarity.
