A device to help with diagnosis and rehabilitation through dynamic visual acuity exercises, quantifying oscillopsies and certain head / eye coordination disorders. Equipped with a high-performance sensor and appropriate software, this new device makes it possible to have :

• A measure of the difference in vision, head fixed and head moving, directly related to oscillopsia complaints

• A measure of the effectiveness at different frequencies of the vestibulo-ocular reflexes in the 3 planes of space, in the planes of the semicircular canals, or during natural movements, at the choice of the examiner using its adapted software. It is a tool for quantifying and re-educating oscillopsies, head-eye coordination, and monitoring progress.
