ABSTRACT:
A lens carrier assembly is adapted for mounting on the vertically movable portion (14) of a vertexometer (18) to allow the user to verify, decenter and apply a blocking device to a lens held in the assembly. The assembly includes a pair of spring-biased arms (2) for holding a lens therebetween. A mechanism (1,3,4,5) for rotating the lens held between the arms (2) may also be provided. A base, having three stages (12, 13, 14), includes joints (15) which allow relative lateral movement between the stages (12, 13) for lateral decentration of the lens. The vertically movable portion (14) of the vertexometer (18) provides the mechanism for vertical decentration of the lens. The decentered lens may be marked for blocking or blocked prior to removing it from the assembly.
