My car mirror doesn't "dim" so I'm gonna try making sunglasses for it. Red to cut the light down to something that won't blind me, laminated with non glare plastic to HOPEFULLY reduce the blinding reflection. If it doesn't work, it doesn't work. We shall see.
Incidentally LED headlights and giant pickup trucks can both fuck off
It DOES cut the light, and the glare, but it makes the reflections so dim and blurry that it's basically useless. A noble failure! I learned a lot. Mark II will be made from dark mirror and antiglare, I have high hopes.
