Fonts for Flyers

What font comes to mind when making a show about eyes? Snellen, of course. Everyone will recognize the "E":

But this particular Snellen font is a bit off. The "E" is right, as are the "C" and the "O", but Snellen eye charts only use certain letters, so that really pathetic "N" is just Snellen's "Z" turned on its side. And the "S" they borrowed from a sans serif eye chart font called Sloan:

Better, but neither the Sloan font nor the title really says "this is a show about vision loss". I could hand-draw the missing Snellen letters, but unless I'm laying things out like an eye chart, it's not worth it.

I also came a across a font called "Colorblind". True to its name, it has no color:

But if I add color to it, it recalls Dr. Ishihara's well-known colorblindness test and then the name makes more sense. Here it is with our image:
