It is better to have ten separate letters of exactly the right size and the same size than a row of letters on one card, as in the Snellen test, otherwise memory will aid the eye, or, as happened recently, a whole class may agree to feign remarkable nearsightedness or farsightedness by confusing letters learned in advance from the card.

"The Adventure of Living"
John St. Loe Strachey
