It's a reference to how Americans rate vision; 20/20 is considered normal, good visual acuity.

But I guess it works if read as a year too.

Yeah, normally I see it written as 20-20 or 20/20, never 2020. That's why I thought it was meant to be read both ways. Pretty good, I think.

[afarrell]

Yes. I intend both meanings simultaneously.
