I am sensitive to LED light and am fortunate to live with a couple of very capable engineers. I'm learning a bit at a time how to work with modern appliances that have a lot of LED lights on them.
I'm going to write up what we're doing here in case it helps anybody else, as I know there are huge numbers of people with the same problem.
My PC is a desktop with a special graphics card that allows it to work with an old fluorescent lit apple cinema screen. I can explain more if needed.
I have a G100 motorola smartphone, which is okay for short use by me, and I can also plug into my pc so I can control it from my computer screen using an application called scrcpy. I was able to choose the smartphone by looking at the pulse width modulation data for the phone on the notebookcheck website. To find the pulse width modulation data there do Ctrl-f and search for "pwm".
Washing machines have just become difficult because they now have control panels backlit with very piercing LED lights which strobe on and off about 100 times a second and when off, their brightness is reduced by 97%. This is basically the sweet spot for triggering migraines.
I have bought one of these washing machines and I can use it because my very smart son had the idea of sticking electricians tape over the buttons and labelling them so we know which one is which. So I can turn the knob and then press the bit of electricians tape to start the machine. This works just fine and means I don't get blasted by the LED lights every time I use the machine. Here is a photo:
The LED clock and the start button are really heinously bright and migraine-inducing. We covered the clock entirely and don't use it. The bottom piece of tape is the start button. If I want to start the machine, I just turn the knob to the correct program, and then press the bottom piece of electrician's tape, and the machine starts.
I haven't decided whether to cover the other lights yet. I probably will.
I can also control the machine from the miele app on my phone, which I can connect to my computer for complete absense of eyestrain. The Machine is a WEE385. It is about the most silent washing machine available too, which really does help a lot.
The next new problem is with cars, in which it's now practically impossible to avoid massive banks for LED backlit screens.
I figured out that answer to this is to buy a Vauxhall corsa. The screens are small and uncluttered in these cars, and if you put the headlights on all the time, then you can dim the screen almost to nothing. With my very sensitive eyesight, I can still read the screen just fine, but it means that it doesn't hurt my eyes. It's possible to buy these as a fully electric vehicle too, so I can be fully modern and do my bit for netzero without having to live with the modern craze for superbright LEDs everywhere. Very happy.
I still having figured out how to sort out the lights in church sancturies other than by asking very nicely for people to turn them off. That is a tricky one.
I had a very very bad street light outside of my house that was truly awful, but the kind people at the LightAware charity sent a legal letter to the council, and the council changed the light bulb to one with a much lower colour temperature, fitting with the conditions suggested in the letter. The new light bulb is fine.
I hope this helps a few people.
Thanks!
