Answer 1

The obvious answer would be to use a B/W imaging system and present the image to your eyes, like with a virtual reality vision system.

If you're looking for a filter that you can just hold in front of your eyes, you can't convert your sight to black and white, but you can convert your sight to monochrome (varying shades of a single color), which is similar, it's just colored instead of shades of gray.

The best filter to use is one called a "monochromatic viewing filter". It can be obtained from photographic suppliers, as it is used by photographers to help them visualize a scene as it would appear on B/W film.

Answer 2

I will tell you the formula but promise me not to ask again to become colorful.
