The invention relates to a medical apparatus for correcting and detecting amblyopia, in particular to an amblyopia correction and detection device based on double-eye balance principle. The device comprises two
liquid crystal lenses, a main plate, two optical sensors and a
control system, wherein the two
liquid crystal lenses are embedded on a lens framework, the main plate is fixedly arranged on the lens framework, the two optical sensors are respectively arranged at the inside surfaces of the two
liquid crystal lenses, the
control system consists of a remote controller which is performed with
wireless communication with the main plate, the main plate is provided with a
microprocessor, a
wireless receiver, a storage card module, a real-time
clock and a
mode selection switch, the
wireless receiver, the storage card module, the real-time
clock and the
mode selection switch are in communication connection with the
microprocessor respectively, the two liquid
crystal lenses are in control connection with the
microprocessor on the main plate respectively, and the two optical sensors are in communication connection with the microprocessor on the main plate respectively. The device has the advantages that the multi-mode amblyopia therapy and correction training is realized, and the therapy and correction training
modes can be freely adjusted according to the
disease rehabilitation state of patients; the device is matched with the
refraction collection and therapy, so the better amblyopia correction and
binocular vision improvement effects are realized.
