Question: 1 / 400

Which statement is true regarding the letters on the Snellen chart?

each letter represents a different size

they are arranged in alphabetical order

letters become larger from top to bottom

even though they each subtend the same amount of arc, some letters are easier to recognize than others

The correct answer is D. This statement is true because even though the letters on the Snellen chart subtend the same amount of arc, some letters are intrinsically easier to recognize due to their shape, the presence of serifs, or how distinct they are compared to other letters. This can affect a person's ability to read the letters accurately at various distances.

Regarding the other options:

A. On the Snellen chart, each letter does not necessarily represent a different size as they are designed to be of the same size when viewed from a specific distance.

B. The letters on the Snellen chart are not arranged in alphabetical order but rather in a specific calibrated manner for visual acuity testing.

C. The letters on the Snellen chart do not become larger from top to bottom; rather, they are designed to be of a consistent size based on standard measurements for visual acuity testing.
