Abstract: A multi-distance testing device includes a testing machine supporting a to-be-tested component, a first guide rail located on one side of the testing machine, a mobile platform connected to the first guide rail and capable to slide back and forth on the first guide rail, a fixing frame fixed on the mobile platform, a display screen fixed on the fixing frame and displaying test charts, a relay lens located between the display screen and the testing machine, and a control system electrically connected or signal connected to the display screen. The relay lens shortens a test distance to construct an infinite test distance in a limited space. The control system drives the mobile platform to move to the first designated position and controls the display screen to switch and display different test charts according to the distance between the display screen and the testing machine.
