I know this is not a great or inexpensive solution, nor does it effectively combat the onslaught of flickering motion on our eyes, but from personal experience, wearing glasses has been my shield of safety while going out and about in the LED wilderness.
I am not affiliated with them in any way, but Avulux is my #1 brand of choice, the only brand I will use from now on, and I've tried several kinds of glasses over the last ten years. These glasses block 97% of light-wavelengths that have been researched extensively to cause migraines in other people with light sensitivities, including LEDs. They really are effective if you can afford them (over $300, sadly, but good quality products that actually work cost money nowadays).
I'm also using the anti-glare lens for the first time, since they had a sale on Black Friday for them, and I recommend those as well. But even without that special coating lens, it makes a HUGE difference for me being around LED lighting, along with other problematic lights, like neon or flourescent lights. They go from being completely intolerable to actually manageable for a while.
I might even have a coupon code still, but it's likely expired by now. Still, I recommend getting some quality glasses that don't just block blue light, but all of the problematic wavelengths that LEDs pulsate out unapologetically. If you are strapped for cash, though, then even getting some effective blue-blocker glasses (key word being effective) can definitely help with the strain. Those and hats and direct avoidance of staring into them…
As for biohacking indoors, you've got the right idea.
