your health

what's TMJ? I grind my teeth all the time. Dentist told me I was losing the sharp part of my fangs when I was a teenager.

ctsai89 You're TMJ is the joint where your jaw meets your skull. Everyone has one (well, two actually)

TMJ disorder is when the nerves in that area become pinched/inflamed and cause issues such as bruxism (grinindg teeth), referred facial pain, and other issues.

Jerry at 30FPS, a game blacks out/erases the whole screen and redraws it 30x per second. web browsers/windows just change the colors of the individual pixels as needed.. plus pwm/temporal dithering

add me to the teeth grinding list. interesting

brain surgery... that sounds very scary

Harrison Good luck

Hi guys, just thought I'd chip in. I'm 33 and I have some of the issues that are described in here. I haven't fully investigated all of them as possible causes for my issues. I suffer from migraines caused by temporal dithering. They are ALWAYS in my left eye. If I push up hard in the top right of my left eye where it meets my nose the pain largely goes away (the nausea doesn't). 30 mins on a Macbook these days can wipe me out for 2 days. I take Sumatriptan as a reliever which works but has undesirable side effects (makes me reallly groggy and slow, not good as I teach music production). I take Propanalol as a preventative, but this has made me gain a fair bit of weight.

With regards to other possibly related issues:

• I have a problem with my temporomandibular - it clicks every time I open and close my mouth. I've always had this. Any thoughts as to what to do about this would be great.
• I get some distortion in my left ear with loud high / midrange frequencies, particularly when my ears has undergone pressure change like having been on a plane
• I also grind my teeth although have never looked into any treatment for this.
• when I take Sumatriptan to cause a migraine I feel like my left sinus clears (like I've taken a bit blast of eucalyptus when I have a cold) and this happens before the migraine lifts

For me prevention is all about avoiding the triggers, but this is tricky since I teach music production and everyone uses Macbooks. Exercise helps but isn't the solution. Hope that helps someone, would be great to put all this data together at some point as there could be something in all this... :]

si_edgey There is so much stuff here that is similar to me. I bet if we talked further we might be able to find more similarities (and maybe connect those similarities). The TMJ, ear problems, hyperacusis (I believe that's what you describe. I have it) are all familiar. Just posting now because I'm not feeling well at all and might forget.

I think a lot of us have TMJ issues. But then again, I think a huge percentage of the population does. I have sinus issues - although not acute, I've been on some kind of decongestant/antihistamine since I was a teenager - and TMJ (I wear a nightguard and that blunts 90+% of the symptoms). But the eyestrain started only about 5 years ago... roughly the same time that I started needing reading glasses.

The #1 co-mordidity I ave seen among LED sensitive folks, and migraine suffers in general, is sinus problems. A lot of the nerves that are involved in the issues we are dealing with run through the various sinus cavities and the pallete/roof of your mouth. I've talked to 2 people who had to have pallete surgery for unrelated reasons and in both cases as a side effect they were completely cured of thier light sensitivity.

If I had to make a rough guess I would say the correlation between folks I have met IRL and online with light sensitivity and sinus issues is over 95%.

This is a good topic to discuss and share. There must a common link, a common factor why all of us gets eye strain, yet other people do not. There must be something that each of us have in common.

Reading this thread, I noticed that many people have sinus. I also have sinus. This could be one of the reason, but I suspect not the main reason. Likely it is a combination of multiple factors, we just dont know what yet.

degen The problem with many low motion blur monitors as they use a PWM type backlight on purpose to reduce motion blur, like a CRT. Many of them are TN panels with dithering too.

Maybe OLED in the future would be a viable option.
