VISUAL COMPENSATION SYSTEM AND BINOCULAR OPTOMETRY DEVICE

摘要

A visual compensation system (10) for observing an optical axis (X) of observation with an optical correction of variable power comprises a first optical element (2) movable in rotation centered on the optical axis (X) and having a first cylindrical power along the optical axis (X), a second optical element (4) movable in rotation centered on the optical axis (X) and having a second cylindrical power along the optical axis (X) and a lens (6) having as axis said optical axis (X) and variable spherical power.
