Surfacing instructions:

This module is incorporated into the Order Entry program. When the operator has finished inputting the prescription details, this module is called in order to produce the surfacing instructions.

The system has been designed to operate in a tele-sales environment, so the time taken to calculate the
SI is designed to be less than two seconds. A summary of the results (base, curves, substance & edge) is shown in the order entry screen. The full details are included in the works docket. There is a facility to see how the SI is calculated on the screen.

The software will calculate the minimum size diameter required. If the lens falls into the stock range and there is a lens in that diameter in stock then a stock lens is chosen. If a stock lens is not chosen then the computer calculates the ideal base from which to manufacture the lens; there is automatic slipping to match the other eye if the prescriptions for both eyes are close.

The software will then use this information as the basis from which to select the blank. If there are blanks from different suppliers in stock then the system will choose according to rules specified by you, e.g. choosing the most expensive in order to reduce the stock valuation. There are options available to try other bases & diameters. The system will automatically try to use a pair from the same supplier.

Surfacing instructions are available for the following lens forms:

Single Vision

Curve Top Bifocal

Flat Top Bifocal

Varifocal Lenses

Plus and Minus Lenticular

Round Segments

Executive Bifocals

Solid Bifocals

Trifocals

The above forms can also be calculated in an Aspheric format and in specified materials and refractive indices.

The computer will also use a frame shape in its calculations. The frame shape can be input from the keyboard (eye size, depth & longest length in the four quadrants), or the system can be linked to the drs Computing digitizer for inputting of drawings, or it may be linked in with frame tracers.

The system also has the facility to include different progressive lens designs for use in its calculations.
