Near Vision Tests

Test Chart 2016 provides a wide range of near vision tests when connected to a tablet.  The patient is handed the tablet and asked to hold it at an appropriate distance.  The practitioner can then change the vision tests remotely from the PC.

Selecting Near Test Mode

When Use tablet is enabled, additional buttons are added to the toolbar at the bottom of the Floating Control Window as shown below:

These buttons determine what is displayed on the thumbnail on the Floating Control Window and on the tablet.

There are two options for the Floating Window toolbar:

• Distance - displays a thumbnail of the distance Test Chart screen
• Near - displays a thumbnail of the tablet screen




There are three options on the Tablet toolbar:

• Remote - displays a remote control screen on the tablet
• Near - displays the current near vision test on the tablet
• On/Off - turns the tablet display on or off




Alternatively, pressing the 0 button under User Defined Tests on the remote will swap the remote function to Near Chart Mode.  Pressing the 0 again will return the function to controlling the distance test chart.  NOTE: This will only work if Use tablet has been enabled otherwise 0 will act as a normal user-defined key.









Selecting a Near Vision Test




The near vision tests are arranged into seven groups:

1. Acuity
2. Tasks
3. Binoc
4. Stereo
5. Amsler
6. DSE (Display Screen Equipment)
7. Misc




The groups are selected by clicking on the corresponding button in the Primary Toolbar as shown below:









The various options available for each test are shown in the Secondary toolbar.  For example, the Secondary Toolbar for the Acuity test is shown below:
