The invention discloses a virtual image distance testing device and method based on a liquid lens and a storage medium. The device comprises a testing lens group comprising the liquid lens, a sensor, a control system and a testing system, the to-be-tested near-to-eye display system is arranged at a preset position in front of the test lens group to display a test image; the sensor is arranged behind the test lens group for imaging; the control system is used for changing the focal power of the liquid lens; the test system is connected with the sensor and is used for acquiring an imaging image corresponding to each focal power and determining the focal power corresponding to the imaging image with the highest definition according to the definitions of different imaging images; and determining the virtual image distance of the near-eye display system to be measured according to the focal power corresponding to the imaging image with the highest definition and the corresponding relationship between the focal pow
