Lens Colour and Corridor Selection

 There is a problem in that too many lenses can clutter up the lens selection lists.  To reduce this, a new CSV file has been created and can work with a reduced lenses csv file. The purpose is to select the lens, colour and corridor and from this create a composite code.

A short code is created to describe the lens and then colour and corridor options are added into the extended file.

For example, the short code for the lens is set as 

ABCDE

It is available in Clear, Brown and Grey.  It is available in 14, 16, 18 corridors.

Theextended.csv file has 4 columns.

Short Code

Short Lens Description

Colours

Corridors

The colours and corridors are colon(:) lists.

So the entry in Extended csv will be

ABCDE,Some Lens name, CLR,BRW,GRY,14:16:18

When a lens is selected then a composite code is created.  If CLR and 16 is selected then the composite code is ABCDEFCLR16.

The colour codes are held in the master treats csv file so that a description of the colour is presented in the selection screen.  The family for these colours should be set to a special code so the treatment does not appear in the usual operation. The usual family code is SPETINT.

Lens with fixed height on the centre line and specifying a specific LTYPE.

 There are some updates to the Technical data.

 A new option has been added for lens where height is not required.

There is also a new field for setting the LTYPE in the OMA files.  An example would be for a lens that is sold as a single vision but NV is to be set as the LTYPE.
