Notes
Important:
The allocation of the numbers to the colors has changed.
This is now valid:
1=glass
2=plastic
3=polycarbonate
4=Trivex©
SF4 had the following definition which is no longer valid:
0=glass
1=plastic
2=composite
3=polycarbonate
The new allocation was made to ensure that the numbers for the material are identical for the lenses and the coatings. (Note: Material as such no longer exists in the Options.Dat file. However, the allocation of numbers has remained in the new version)
Hard coating incl.”, “Clean coating incl.”
The fields “Hard coating incl.”, Clean coating incl.“, etc. are assigned with value 1 if these extras are supplied automatically, i.e. if no IT code for the option/coating is transferred with the electronic order.
Principal Meridian check incl. Add.
If this field has the value “True”, the near value of the lens (SPH + ADD) has to be used for checking the power range.
Example:
Delivery range PM -4.00 bis +4.00 Sph -4.75 Add. 0,50 --> KO (-4,25) Sph -4.50 Add. 0,50 --> OK (-4,00) Sph -4.25 Add. 0,50 --> OK (-3,75) Sph -4.75 Add. 0,75 --> OK (-4,00) Sph -4.50 Add. 0,75 --> OK (-3,75) Sph -4.25 Add. 0,75 --> OK (-3,50) Sph +3.25 Add. 0,50 --> OK (+3,75) Sph +3.50 Add. 0,50 --> OK (+4,00) Sph +3.75 Add. 0,50 --> KO (+4,25) Sph +3.25 Add. 0,75 --> OK (+4,00) Sph +3.50 Add. 0,75 --> KO (+4,25) Sph +3.75 Add. 0,75 --> KO (+4,50)
Price determination for Principal Meridian check incl. Add.
If the field has the value „true“, then the near value (sph+add) is used for pricing.
Example:
The following price groups exist:2, 4, 6 Sph: +3,75 Add:0,5 → The lens is in price group 6, da +3,75 +0,5 = 4,25 (Near value) Sph: -2,25 Add:0,5 → The lens is in price group 2, da -2,25 +0,5 = -1,75 (Near value)
