Lens Material
Lens Style
Lens Treatment
Lens Tint
Required if you are ordering lenses.

Refer to catalogue reference, under the lens section.  This is the code from the catalogue
which specifies the lens product to order.
NOTE: you may use _LSTYLE, _MATERIAL, _TINT and _TREAT in lieu of the _LCODE
In our experience, it is easier to use the other labels than using _LCODE. 

You may also use UPC with the UPC translation table to specify materials, lens styles,
tints and treatments, as well as addons.
