As instructed by the screen prompts, load a block and pad onto the blocking arm chuck and place the 
lens to be blocked on the glass plate in the blocking chamber.  The Clarity automatically detects that a 
lens has been loaded and displays two additional control buttons at the lower right: 
 

START – Initiate the lens analysis/verification and blocking process. 
Manual Alignment – Perform the lens alignment manually prior to blocking. 

 
Select START to identify features of the lens and perform lens analysis.   
 
The Manual Alignment button can be used instead of the Start button when a progressive is 
known not to align properly.  You can choose Manual Alignment and not have to wait for 
analysis to proceed. 
 
 

 
 The Analysis screen will appear and show the prescribed Rx information on the left side of 
the screen and the measured information on the right side of the screen.  Once the analysis is 
complete, the measured information will be checked against the prescription to determine if 
the lens meets ANSI standards.  If the lens does not meet the tolerances, the individual 
parameter(s) that are out of tolerance will be displayed in red.  Those that fall within the 
standards will display in black. (See Fig. 2.3.)
