I believe this has been discussed in other threads here, especially those pertaining to heterophoria, but I wanted to open the discussion up as much as possible, because it seems quite remarkable to me how similar these symptoms are to what I experience when looking at a problematic device. I experience strain in muscles around my eyes (usually one eye is much worse than the other), and face pain. It seems worse at night (larger pupils?), and if wearing sunglasses. Speed plays the biggest role. It starts at 70-80 km/h, and increases further with speed beyond that. Quite painful at 100 km/h and up.
How could driving at high speed trigger the same symptoms as looking at a device with PWM or temporal dithering?
