Near Vision Test

If required, perform a Near Vision test with a test chart on a Near Vision rod.
1. Insert the Near Vision rod and test chart into the Convergence Lever on the bridge of the
Phoroptor Head if it not already in place. The thumb screw in the center of the Convergence
Lever is used to loosen or secure the Near Vision Rod.
2. Touch NEAR on the menu bar at the bottom of the main screen.
3. Lower the Near Vision rod.
• The ADD boxes are highlighted.
• Both apertures are open.
• Both refractor halves converge to 15.75 in. (40 cm).
Note: The Reading Card automatically illuminates when the Near Vision rod is lowered.
4. Press the illuminator light button on the underside of the Card Illuminator to adjust the light level.
Note: The illuminator light has two intensity levels.
5. Turn the CONTROL KNOB to the right to add power in 0.25 D increments.
Note: Ensure that the patient's forehead is positioned against the forehead rest.
6. When the Near Vision test is completed, raise the Near Vision rod. The ADD boxes are no
longer active and the ADD power is removed.
Note: If the ADD data fields are activated and the Near Vision rod is not lowered, a
"Convergence" message appears at the top of the screen, reminding you to lower the
rod.
Note: If the Near Vision rod is not raised after completing the test, a message appears at the
top of the screen.
