Because the Optivision system is easy to
understand, simple to use, and truly user-friendly, your
learning time is greatly reduced and the initial impact
of computerizing your lab is minimized. Your lab is quickly
up and running, and you can immediately realize the value
of the system as you see results in increased productivity.
One of the major objectives of the Optivision Laboratory
Management System is to reduce errors in the order entry
process. Wherever possible, data is checked during entry.
For example: powers must end in .00, .12, .25, .37, .50,
.62, .75, or .87; adds must end in .00, .25, .50 or .75;
axis must not exceed 180 degrees; plus and minus signs on
cylinders are verified. A warning is posted on the screen
when an error is caught, and a correction must be made before
the operator can continue.
Segment heights may be entered as actual heights or as
so much above and below, such as "21" high or
"-5" below. Heights of the optical center in single
vision lenses are entered as an amount above the bottom
of the frame.
Most lenses today have OPC bar codes printed on their packages,
and many frame manufacturers are complying with this standard
as well. Optivision software makes the maximum use of these
bar codes in order entry and inventory management.
The lens OPC codes are scanned at the time an order is
entered. The following lens information is brought into
the order from a database:
Designation of finished or semi-finished
Scratch coated or not
UV coated or not
Base curve or sphere power
Add or cylinder power
For a right or left eye
As all of the above occurs, the lens is also taken out
Optivision software has two order entry systems. One system
operates on the basis of a qualified person choosing the
lenses to be used for the Rx and the order is entered using
the bar code reader to bring in the lens parameters. This
option prints a shop work ticket when the order is entered.
The other system assumes that the program will choose the
lenses and produces a lens pick ticket. The lens pick ticket
lists the material, index of refraction, lens type, base
curve, add, power of usable stock lenses, and the exact
location of the lenses in the stock room, quantity on hand,
or if none on hand, how many are on order and when ordered.
If you do not normally stock the lens, the system reports
the OPC code of a lens that will work for the order, letting
a clerk add it to the lens ordering system.
If the Rx is being entered from a lens pick ticket, the
stock room clerk will put the lenses selected in the tray.
Using a bar code wand, the clerk scans the tray, then scans
the right and left lenses. The system will check to see
that the lens picked conforms in all pertinent respects.
The following items are verified:
Lens index of refraction
Base curve (within +/- 1.00 D.)
Sphere, if stock lens
Cylinder, if stock lens
Right or left eye correct
If an error has been made in picking the lens, the system
will print a list of the errors. Otherwise, the system will
print a shop work order with all of the surface and bench
If any of these parameters become acceptable, such as a
doctor-approved change from FT25 to FT28, the error warning
may be overridden and the order will be changed accordingly.
The lens OPC codes are a very important, integral part
of the Optivision system. They facilitate fast, accurate
order entries and are vital to comprehensive inventory management.
If your company sells stock finished lenses, the bar code
reader really simplifies the process. It lists the lenses
bar-coded and invoices them for you on an invoice that allows
you to put the patient's name and tray number on it for
The Optivision system has a maximum/minimum system for
"just-in- time" inventory. As each Rx or stock
order is entered, the on-hand quantity is reduced, and when
this quantity reaches the minimum, the system reorders it
back to the maximum. At the operator's command, an order
is created and printed out by vendor for you to verify and
add or delete items. After the order is ready, it will be
transmitted automatically to the vendors that have the facilities
for electronic ordering.
Through the OPC codes on lenses, frames and trays, the
Optivision software performs the following:
Removes items from inventory
Returns items to inventory
Transmits the orders directly to the vendor's computers
Gives product usage analysis reports
Prints a production cost analysis report
Prints a product usage analysis report by customer
Provides an inventory master report with quantities on
hand and their dollar value
Tracks the order through the lab (required hardware additional)
Creates a history of each order (how many times and when
the order was at a work station)
Changes in the order that occur after the order has been
entered are easily made without reentering the entire order
again. On command, the system replays the original order,
allowing the changes to be made, and then a new work ticket
reflecting the changes is printed.
The Optivision lens grinding specifications are derived
from mathematical, trigonometric, algebraic, plane geometry
and physics calculations on each and every lens, not from
some "grinding chart." These original calculations
make Optivision software one of the most accurate systems
on the market today. Reduction of spoilage is very important
to keeping your profits high, and the Optivision system
strives to maintain accuracy throughout the system.
