Abstract: An optical lens assembly is adapted for receiving a light beam that is emitted by an object, and includes a lens unit and a sleeve unit. The lens unit includes a casing that has a light-incident side adapted for receiving the light beam. The sleeve unit surrounds the light-incident side of the casing, and defines a light-receiving space that is adapted for the light beam to pass through so that propagation of the light beam is unaffected by disturbance caused by movement of air. An optical measurement method includes steps of: a) providing a lens unit, a sleeve unit, and an object that is for emitting a light beam; and b) operating the lens unit so that the light beam is received by the lens unit.
