Chapter 1 – Getting Started
The Clarity Automated Lens Analyzer/Blocker is designed to verify all prescription
parameters including sphere power, cylinder power, axis, optical center location, prism, and
all add powers as well as thickness and front curve information. It will also affix a finish
block to the lens on axis at the geometric center of the frame shape. It is shipped in an almost
ready-to-run condition. This guide will allow you to put the Clarity into service quickly. We
will cover the following topics:
• Unpacking the Clarity
• Applying power and turning on the unit
• Connecting the unit to your lab’s computer system
• Using the touch-panel display and examining some of the operator screens
• Operation including lens insertion and blocking
• Calibration
• Advanced screen functions
The Clarity has many features and settings to allow you to optimize it for your specific lab
environment. It also has diagnostic capabilities and adjustments to fine tune its operation.
This guide does not describe all of the features or adjustments. Once you have become
familiar with operation as described in this guide and want more information, call Technical
Support.
Unpacking the Clarity
The Clarity is shipped in molded foam blocks within a cardboard carton. These blocks need to
be removed prior to removing the machine from the carton. An accessory kit is shipped in
two small cardboard inserts. The shipping carton and shipping materials should be retained in
the event that the unit must be shipped again.
Before removing the Clarity from the packing box and setting it up, please read this guide and
familiarize yourself with the accessories, features and terms used throughout the guide. There
is a glossary of terms in the back of this guide. Once the carton is opened, remove the two
inserts containing the power supply, power cord, and accessory kit. Remove the two side
panels and lift the unit out of the carton. Be careful to use the appropriate lift points. (See
Fig. 1.2) Place the unit in the desired location, but out of direct sunlight.
Inspect the contents to ensure you have all the items listed below. (See Fig. 1.4). There
should be 14 items in the two inserts. They are:
1. Power supply
2. Power cord
3. 70mm Plano CR39
4. 70mm -6.00 CR39
5. 65mm +6.00 CR39
6. 58mm calibration disc
7. White marking pen for progressives
8. Oval calibration template with permanent block attached

12. Light shield (left gripper)
13. Light shield (right gripper)
14. Bag of screws for the light shielding
15. Clarity User Guide (not shown in Fig. 1.4)
When the Clarity is prepared for shipment (by the factory or the user), its mechanism must be
secured against movement caused by jarring or shocks to the shipping carton. Units may use
one of two means for doing this: (1) molded foam blocks within the blocking chamber, or (2)
a clamping device attached to the blocking mechanism. In either case, the shipping restraints
must be removed prior to using the Clarity, and must be re-installed prior to shipping the unit,
should that prove necessary.
CAUTION
Shipping the unit without properly re-installing the factory shipping
restraints may cause severe damage to the equipment.
Foam Shipping Blocks in the Blocking Chamber
Remove the two foam blocks that hold the mechanism in place during shipment. Note how
they are installed in the event that the Clarity needs to be shipped from your location. Call
Technical Support for help in packing the machine for shipment. Figures 1.1a and 1.1b show
how the foam shipping blocks are installed.

The Shipping Bracket assembly is shown in Figure 1.1c. The Foot is placed on the base of
the blocking chamber. By squeezing the Pinch Lock, the Pinch Rod may be moved up or
down so that the cutout in the Plate engages the chuck and the Locating Pins engage the
bottom of the blocking mechanism. When installing the assembly, the Pinch Lock mechanism
should be moved downward so that the rubber Foot is slightly compressed. Figure 1.1d shows
the shipping bracket in its installed aspect.

Figure 1.5 – Installing the Glass Plate
Installing the Glass Plate – The glass plate is placed over the opening in the base plate of the
blocking chamber. Clean the glass plate and then slide it into the pocket. It should fit and
seat down in the pocket fully. (The glass plate is shipped in the accessory box.)
Installing Light Shielding – This shielding is designed to reduce or eliminate light coming in
to the blocking chamber causing inconsistent lens analysis. The shields are not necessary in
all lab environments. Only if you see white or clear areas on the lens image (on screen)
during processing should the shields be needed. They are in the accessory box in the event
that there is too much light entering the chamber. There are three separate parts to the light
shielding including the left gripper shield, the right gripper shield and the blocking arm shield.
The left and right gripper shields can be installed using the screws in the accessory box to
secure them to the tops of the front gripper arms. There are two threaded holes for the screws
to attach the shields to the tops of each gripper arm.
The blocking arm shield requires that you remove the center screw of the blocking arm,
thereby removing the chuck. Place the shield over the arm with the flat side facing down.
Replace the chuck (align small hole on the back of the chuck with the locator pin) and insert
and tighten the center screw.

Chapter 2 – Basic Operation
WARNING
Use only a grounded outlet. Do not defeat the grounding by cutting off the
grounding prong on the power cord, or by using a non-grounding adapter.
NOTE
The power supply module is designed to work with both 115 VAC (60 Hz) and with
230 VAC (50 Hz). A separate power cord is available for each application. In the
U.S., units will be shipped with 115 VAC power cord unless otherwise specified.
WARNING
The back case top should not be removed while the machine is powered ON. Power
the machine OFF and unplug from the wall.
Powering on the Clarity
• Make sure that the Clarity main power switch is in the OFF position. The side of the
switch with the symbol 0 should be depressed.
• Plug one end of the AC power cord into the power supply module. (Fig. 1.3)
• Plug the other end of the AC power supply cord into a grounded outlet.
• Plug the power supply module into the power socket on the rear connector bulkhead
shown in Fig. 1.3.
• At this time you can connect a serial cable for communications from the host computer to
COM 1 or COM 2, 9-pin serial port on the rear bulkhead. This method will require the
use of a null modem at either end of the serial cable.
• Once the unit is properly plugged in, both at the machine and the wall, press the left side
of the power switch (with the symbol l) to apply power to the Clarity. Within 6 to10
seconds, the display should become active and the mechanism should move to locate its
home position.
• Either of the two 9-pin serial ports on the rear bulkhead labeled COM 1 and COM 2 (may
show up in the Interface tab as COM 5 and COM 6 respectively) can be used to set up
serial communications.
Establishing Communications
At this time, you will want to set the communications to your lab software. From the Job
Screen, press EXIT, then select Setup, and then select the Interface tab. Choose the VC
Connection Method, and then set the Baud Rate and COM Port if you are using a serial
Clarity User Guide, March 1, 2011 - Rev. 1.06

connection. If you are using an Ethernet connection, then you must set the two ports in the
TCP/IP Network Auto-Connect Settings box.
CAUTION
Keep hands away from unit during the blocking function.
The Touch Screen Display and Job Screen
CAUTION
Do not use a sharp object (pencil or pen point, paper clip, etc.) on the touch screen as it may
scratch or tear the screen. Clean the screen with a microfiber cloth such as is used to clean
eyeglasses. A soft cloth slightly dampened with clear water may be used for hard-to-remove
spots. Turn the Clarity off before cleaning the screen.
The Clarity is equipped with a touch screen display. A mouse and keyboard can be installed
on the rear bulkhead if desired. A mouse is recommended to have at all times for manual
alignment of progressives, bifocals and trifocals. There are two USB ports that can be used as
well as two PS-2 connectors at the rear of the machine. (See Fig. 1.3) If you install a PS-2
mouse or keyboard while the machine is ON, you will have to reboot the machine (cycle the
power OFF and then ON) for the machine to recognize
there is a device connected.
Once the unit is powered ON, it will boot to the main Job screen. (See Fig. 2.1.) The
program will open, initialize communications, and the camera will go through several checks.
Fig. 2.1 - Job Screen
Clarity User Guide, March 1, 2011 - Rev. 1.06
Page 14
When a Job Number has been entered, the EXIT label on the control button changes to
PROCESS. Jobs are processed in one of the following three ways:
1. You may enter the job number manually with the touch screen keypad or keyboard
and then select PROCESS.
2. You may use USB barcode reader and scan a job number into the machine and then
select PROCESS.
3. You may enter multiple job numbers either manually or with the barcode reader by
going to the Preferences tab in the Setup menu and checking the box labeled Enable
Batch Blocking and activating Last in First Out, or First in First Out.
NOTE
Selection 3 above allows the operator to enter a large group of jobs (like a stack of trays) for
efficiency. The Clarity will then bring up each job in the order that was specified in the setup.
(See batch blocking in the glossary.)
The Processing Screen
From the Job Screen, press the PROCESS control button to gain access to the Processing
Screen (Figure 2.2).
Figure 2.2 - Processing Screen
When the screen is first displayed, only two control buttons are shown in the lower right:
Switch Sides – Change displayed eye to the opposite side. OD is displayed initially.
Cancel – Return to Job Screen.
Clarity User Guide, March 1, 2011 - Rev. 1.06
Page 15
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
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.)
