See https://FlickerSense.org for a PhD scientists personal account, and, https://LEDStrain.org forum full of people that get migraines, dizziness, eyestrain and headaches from LED lights and other forms of flicker like temporal dithering.
It triggers migraines (or vestibular migraines), tension headaches and dizziness in a minority.
See https://www.change.org/p/apple-add-accessibility-options-to-..., or FlickerSense.org, or LEDStrain.org forum.
Also a PhDs website: www.FlickerSense.org
It causes a minority of people eyestrain, vertigo and migraines. See LEDstrain.org.
There is other stuff they can do, like a toggle to disable temporal dithering. Or actually test their devices with people with binocular vision dysfunction.
There is a whole community of people on LEDStrain.org who suffer from severe eyestrain, vertigo, headaches and migraines to the point where these devices are unusable for a minority of people.
One possible cause is temporal dithering which can be seen as the dancing pixels on a slow e-ink display: https://youtu.be/0y-I3hqQgCQ. Windows also uses this technique, but Apple's causes more strain for some reason.
It would be great if apple could look into this.
Some of us are desperate and will gladly pay for help. I am at risk of losing my IT job cause of these companies. I have a binocular vision dysfunction but treatment is not working well.
Any ideas from the community as the technical root cause?
Edit: not sure why I am being downvoted. Please have some empathy!
The Neurolens are also unfortunately very expensive and seems to not be covered by insurance. But I think most people would gladly pay out of pocket to get relief. I surely would.
We actually have a discussion about Neurolens on LEDStrain: https://ledstrain.org/d/754-trigeminal-dysphoria-and-neurole...
I plan to give them a try. But unfortunately it does not work for everyone.
Have you had success with them? Many other members have convergence excess (esophoria) or vertical heterophoria.
It is likely other sources of flicker like temporal dithering (FRC), you can see it here (it is on Windows too): https://youtu.be/0y-I3hqQgCQ
The visual noise/dots you see is the dithering. The e-ink display is slow enough so we can see it.
People with BVDs are strongly affected by that noise...and unfortunately simple pair of glasses does not help.
A minority of people have binocular vision dysfunctions (like convergence insufficiency) that give them severe eyestrain, headaches and migraines when this flicker occurs. Apple should treat this like an accessibility issue (like VoiceOver) but does not. The current treatment from behavioral optometrists is not always effective.
I recently found a whole community on this: https://ledstrain.org.
If you have expertise in displays, please join us on LED Strain! We were hoping Apple would address these accessibility issues and let people with vision problems use their products.
The google customer experience is just horrific.
The call volume itself looks suspicious. No calls for well over a year and then suddenly an incredible amount? You would think Google would have some algorithm to detect this?
