Do you wear sunglasses when you ride? If not, maybe they would diminish the flashing/strobing affect. Or if you do wear them, maybe a darker lens would work. By the way…I’m not a medical professional, but is this perhaps something you should see a doctor about??? A few times (and I’ve heard this from other cyclists) people will say to me that the blinking of my bike light can trigger epileptic seizures. And speaking of blinking bike lights — I have a white light headlight that I switch on in the late afternoons as the Sun begins to set. I generally set it on blinking mode at first…while there’s still light in the sky…and I can’t actually see the flashing light on the surfaces around me. I feel that at that time of day the blinking light is more noticeable to drivers than a steady beam. But when the Sun goes beneath the horizon, and the ground becomes darker, the flashing becomes more and more noticeable. It doesn’t (or hasn’t yet) caused any of the symptoms that you mentioned about the flashing sunlight through the trees. But, it does become very annoying to me. Then at some point I switch the light to a steady beam because the flashing is such a nuisance. Anyway…maybe the sunglasses might diminish the problems you’re experiencing. Good luck.
