Reichert ClearChart® 3P Polarized Digital Acuity System
Reichert ClearChart 3P provides you with an extensive variety of optotypes, which can be easily accessed with the infrared remote control (included), or through the Reichert Phoroptor VRx, Automated Refraction System controller. The Clear Chart 3P is also accessable through Reichert Auto Phoroptor RS, Visutron 900+, or Visutron 900 Touch. Optotypes can be randomized, increased, or decreased in size through either interface.
The Reichert ClearChart3P offers the same features and employs the same reliable operating system as the ClearChart2, but with a larger 24”(1920x1080 Pixel) backlit LED screen, as well as fusion, stereopsis and other special test charts.
Because the Reichert ClearChart 3P is used in different parts of the world with specific acuity notations and optotype size progression requirements, it is available with 3 different remote controls:
Installation is easy. To set up the Clear Chart 3P for a single mirror system, simply use the arrow keys on the remote to enter the distance from patient to mirror and ClearChart to mirror. Letters are perfectly sized, automatically. Direct throw is even easier.
Optotypes:
Color Testing: The COLOR button accesses the test charts for color vision testing. A selection of twenty four charts is available for testing color vision deficiencies. These charts are digital renderings of the American Optical H.R.R. Psuedoisochromatic Plates
EDTRS: The ETDRS button accesses optotypes with sloan letters and logmar progression that meet specific standards for ETDRS testing. Three standard ETDRS charts are available.
Astigmatism: The ASTIG buttons displays four different charts for astigmatism testing.
MKH Phoria & Stereopsis: The MKH button displays a series of eleven different test charts used for phoria and stereovision testing.
Schober Test: The SCHO button accesses the Schober tests for binocular balance and suppression testing
Cross Grid Chart: Press the GRID button to display the Cross Grid Chart
Dark Screen: The DK/MDX button displays a dark screen. A second press of the button will illuminate the Maddox LED

Crowding Bars: The CBAR button places crowding bars around a letter optotype
Suppression Test: The SUPP button presents an alternative suppression test with white letters on a black background. The first button press will display a line of 5 letter optotypes with the first and last optotypes in red and green, reading from left to right. A second button press will change the position of the red and green opotytpes.
Polarized: The P(MUSC) button displays three different polarized muscle balance tests. Pressing the RIGHT arrow button displays each chart. The (P)BAL button accesses three different polarized binocular balance tests. Additional polarized test charts can be displayed by pressing the (P)OLAR button. These charts include the Mallet Test and Horizontal and Vertical Coincidence Tests.
Reverse: The B/W button reverses the contrast on the display. Press the button to toggle between black letters on a white background and white letters on a dark background.
The last row of buttons on your remote control allows you to present lines of the same size of optotypes, present lines of optotypes in descending size, and present a single vertical line of optotypes. A second press of this last button displays a single vertical line of optotypes of descending size.
