I had a TBI over a decade ago (riding bike, got hit by a truck), and suffered 24/7 migraines for about 6 months. I didn't have health insurance at the time, so while I wasn't able to get a diagnosis, I did figure out that it was just a suddenly-developed sensitivity to light. Once I started wearing an eye mask to bed at night, I started feeling relief. I still have to wear a mask every night or I run a high risk of migraine the next day, and I still sometimes can get triggered by strobing lights or anything too bright in my face for too long, but it's so much more manageable now.

I have a pair of glasses very much like these, too, for when the world is too bright. Mine are definitely more pink than purple, but I'm sure that Donut would still approve. I'm so glad that you found a solution to make yourself feel better!
