I want to build "passive" glasses that allow you to see the world in black and white, just for fun.

"Passive" stands for "no digital technologies". I read a lot of "nos" and "notpossibles", but I still decided to find a way how to do it. If it's easier, we can start with any glass, not necessarily glasses. That includes mirrors, too. No material, thickness, or size limit. Let's see what you got!

Glasses with a heavier tint of black

Indeed very tough! I was thinking of the potential areas where such material could exist (in nature as well as existing technology) but could not find any. Those in technology are digital and those in nature are not monochromes. I thought of animals that have black and white vision (most animals). However, animals do not "see" things as black and white. It is their brain that processes the images and presents them as black and white. So, no such material will exist in nature, is what I think.
Then, I found this. Such glasses, although cannot eliminate other colors, can maximize one color. For example, through these glasses, objects appear more "rose" and less other colors. Similarly, what if you use black-colored glasses with a heavier tint of black. They may not eliminate other colors (so not 100% accurate) but black would essentially be more and all objects would appear a few shades darker, getting close to black and white. You could not wear them at night or in dimly lit places.

Cool, those look interesting. I wonder what's the physical mechanism behind it.

Juran Here is an example of how an increase in black color opacity changes how things look through it. This is how they tint the glass, by attaching a synthetic sheet to it. Gradients in the color exist.
