Convenient to use with detailed distance adjustment
Within a range of 2.5 to 6 meters, the examination distance can be adjusted with precise increments of 0.1 meters. Additionally, for installation in examination rooms where the minimum distance of 2.5 meters cannot be maintained, a mirror function is provided to view the charts.
Supports accurate vision testing
The HDC-7000 provides 41 charts for vision measurement, allowing for binocular balance tests, stereo tests, fixation disparity tests and fusion tests. For binocular testing, the red/green colors can be adjusted to match the filter's color, and the contrast of the chart can be adjusted for more accurate testing.
Usable on LCD monitors of various sizes
The HDC-7000 can display charts using various sizes of LCD monitors, including 17”, 19”, 20.1”, 23”, and 24”. To ensure accurate symbol sizes on each LCD, users need to configure the monitor size and resolution in the user menu.
