Is there any way to protect against turn signals?

I have polare sunglasses, over my regular glasses, but they aren’t enough.

Flashing lights such as turn signals and other safetyweapons blind me, disorient me, unbalance me, and sometimes trigger my migraines and vomiting. Fortunately I don’t get seizures.

Flashing lights from two or more directions, such as turn signals at intersections, often blind me, disorient me, and unbalance me into stumbling into the street.

I try to avoid crossing at busy intersections, but I still have a lot of trouble, and I have been hit by a car [last June] while crossing at a crosswalk between intersections.
