1. Introduction
1.1. Outline of product
The Huvitz Digital Chart (HDC-9000) is a computerized chart presenting device that provides charts for
refractive correction test and various functional tests such as cross cylinder, red/green, binocular balance,
fusion and suppression, heterophoria, associated phoria, aniseikonia, stereopsis, and dominant eye test
for heterophoria. Since the Digital Chart implements charts on the LCD panel by exploiting the cutting
edge digital technology, it’s not only faster and quieter but also equipped with multifarious convenience
functions. The contrast sensitivity and the background luminance of the chart are adjustable for
environmental needs. The chart can be installed in a wide range from 1.5 to 6 meter. The distance
between optotypes can be set to variable distance and even the selection of optotype can be randomized.
Also the image gallery contains a dozen of image clips that the examiner could utilize during the
examination. Various masking and random functions would be helpful for a punctual vision test.
The examiner may execute all the charts and functions by using the remote and the buttons on the main
body of the digital chart. If the chart is connected to the Huvitz Digital Refractor, the examiner would just
use the Operation Panel of the Digital Refractor for chart operation as it allows to control the lens unit and
the chart device at the same time by a touch of buttons on it.
