What font is used in eye exam charts?!
Question: Any info you have (not just guess - I've got that covered, thanks!) on why that particular font is used would be appreciated.

It depends on the chart. Distance charts use all capitals.
Block fonts without serifs and with each letter all occuping the same amount of space are used so that sizing works out.
Near charts use a variety of fonts.
See the link below for a discussion of factors considered in designing acuity charts.
Since it looks pretty basic, I'm thinking something like Verdana.
The font must be Courier (or Courier Bold) in order for the "font size" in points to correspond to the indicated letter height. Courier Bold is the PostScript font that most closely approximates the official Snellen letters.
