Diagnosis
Vision Test
The vision test is one of the simplest yet most important components of
the eye exam. In order for eye doctors to compare results, it’s always
done at a standardized distance of twenty feet. Old-fashioned offices had
rooms that were twenty feet long. Today, mirrors are used to reflect the
image so the room can be shorter; but the image still looks like it is twenty
feet away. The charts are standardized too and doctors around the world
use the same basic format.
