Single Vision Prism - Finished lenses - When considering finished lenses during blank selection, these settings control whether or not there may be prism at the major reference point on the lens. The amount of prism allowed will be based on the prism allowance for the order’s account.
No prism allowed
Prism on full service and uncuts
Prism on full service only
Prism on uncuts only
Selection List Sort Order:
Sort by base curve / in-stock - This setting controls the sort order for available blanks by base curve / in-stock. If selected, a blank with the optimal base curve will be higher in the blank selection list even if it is not in stock. This would most often be used in cases where the lab orders lenses daily and prefers to order the optimal base curve even at the expense of waiting an extra day to manufacture the lens.
Sort by in-stock / base curve - This setting controls the sort order for available blanks by in-stock / base curve. If a lens with the optimal base curve is not in stock, a lens with a similar (but less optimal) base curve that is in stock will appear higher in the blank selection list. This would be used in cases where a lab either does not order daily, or lenses take more than a day or so to arrive after being ordered, and the lab would prefer to begin manufacturing the job before the ideal lens would arrive.
Force SRC blanks when AR requested - If checked, this option enables selection only of scratch coated blanks if AR is requested on the job. Uncoated blanks will not be considered for blank selection if any AR coating is requested on the job.
In order for this option to work, the pretreatment code(s) on the lens(es) considered must be identified as scratch coating, and the pretreatment or addon used on the order must be identified as an AR coating.
On the pretreatment file, the question “Is this an anti-reflective coat” must be set to Y.
In the case of an addon, the job flow flag “AR COATING” must be set to Y.
Force semi-finished/ finished selection - This field contains whether or not a finished blank could be selected for one eye and a semi-finished for the other. When checked, both blanks must be the same. When un-checked, Rx-Universe could pick a finished blank for one eye and a semi-finished for the other eye.
Create blank selection log file SURF\order.SEL - If checked, each time a blank selection is done for an order, entries will be added to a file named ordernumber.SEL, located in the SURF folder under the root Rx-Universe folder.
This option should only be checked when trouble-shooting is being done on blank selection problems at a lab. Note that .SEL files created with this option will need to be manually removed once they are no longer needed.
Blank size force allowance - When a specific lens diameter is entered on the order screen, the blank selection process will check for lenses based on the setting of this field
When set to “0”, the selection process will look for a blank size of the entered diameter or larger. When set to “1”, “2”, or “3”, the selection process will look for blanks of the exact diameter or blanks with a diameter +/- the set allowance. ie: Is set to “2”, and the diameter selected is 70 mm, lenses from 68 mm to 72 mm will be selected.
Split base power difference - This value will determine when to use the same base curve for both eyes when the Rx power is different enough that it would normally select different base curves for each eye. When different base curves are called for due to the difference in Rx powers between the eyes, a laboratory will often want to grind both lenses on the same base if the powers are within the range set by this field. The base that will be used for the lenses is controlled by the “Base Rounding Method” setting. When comparing the powers of the left and right lenses, if the difference between sphere powers of the left and right lenses, or the different between (sphere + cylinder) between the two lenses is greater than the difference specified in this field, then different base curves will be selected for the two eyes.
Base rounding method - This controls which way to round the base when a common base will be used for two lenses with different powers that would normally be run on sperate bases.
Up - Both lenses would be run on the higher base.
Down - Both lenses would be run on the lower base.
Average - Both lenses would be run on an average base.
0 thru 9 - Both lenses would be rounded toward the number selected.
Check QTY on hand - When selecting blanks, this setting checks the quantity on-hand when considering lenses.
Select all valid lenses - ignores the quantity on-hand. This is used when the lab does not wish to track actual quantities on hand, and will select the “best” lens for a job, ignoring whether it is in stock or not.
Select valid lens if in-stock - checks the quantity on-hand before selecting the lens. Generally speaking, lenses that are in stock will appear higher in the blank selection list than lenses that are not in stock - this would only be used by labs who are tracking inventory levels.
Check in-stock for semi-finished only - checks the quantity on-hand for semi-finished lenses, this setting will cause a finished lens to be ordered before using a semi-finished in-stock lens. This would be used when a lab can order an out-of-stock finished lens and expect to receive it the next day; it avoids surfacing a job that can be done with finished lenses.
Select only in-stock lenses - only blanks that are in-stock will be added to the blank selection list. Any blank not in-stock will not even appear as an available blank in the blank selection list. This would be used by a lab that orders blanks on a longer schedule, perhaps monthly. Because ordering any out of stock lenses would take weeks or longer to come in, the lab wishes to use only blanks that are in stock to manufacture jobs, even if such blanks might be less than optimal.
Finished Lens Tolerance:
When considering a finished lens, Rx-Universe will look at the desired center, edge and drill point thicknesses for a surfaced blank in the power, frame dimensions, and decentration required for the job, and compare the resulting thickness of a particular finished blank with those target thicknesses. The tolerances below are then used to decide if the finished lens is acceptable based on the thickness rules.
Thinness tolerance - This is the lower limit for lens thickness when selecting finished lenses. If the center, edge or drill point thickness of the finished lens is thinner than the target thickness by no more than this tolerance, the lens will be used. If the finished lens is thinner than “target thickness - thinness tolerance”, then the finished lens will not be selected.
Thickness tolerance - This is the upper limit for lens thickness when selecting finished lenses. If the center, edge or drill point thickness of the finished lens is thicker than the target thickness by no more than this tolerance, the lens will be used. If the finished lens is thicker than “target thickness + thickness tolerance”, then the finished lens will not be selected.
Safety Thinness tolerance - When considering finished lenses for Blank Selection, this controls how much thinner than the requested thickness the finished lens can be and still be acceptable. This setting is used for safety jobs only.
Safety Thickness tolerance - When considering finished lenses for Blank Selection, this controls how much thicker than the requested thickness the finished lens can be and still be acceptable. This setting is used for safety jobs only.
Match Front Curve Tolerance - This setting controls the maximum difference between the True Front Curve of the lenses for the lenses to be considered as having the “same base curve”. The allowable range is from 0 to 9.99 diopters.
