Lens Calculations & Rx Layout

Optifacts Lens Processing Features

  • Geometric Center (On-Center) or Optical Center (MRP) blocking.
  • Reduces and often eliminates prism grinding by utilizing oversize blank area on single vision lenses, including prescribed prism.
  • Automatically determines correct tools, effective prism grinding, and thickness for any index lens material.
  • Compensates prism on Rx's using prism rings.
  • Eliminates common power errors on high-minus CR-39 and polycarbonate lenses.
  • No manual curve entries needed for aspheric lenses.
  • Considers all types of slab-offs. Manufactured (including reverse slabs) and Rx-ground slabs have separate routines for accurate thickness control.
  • Recommends maximum block size, reducing high-cost replacement of blocks and generator wheels.
  • Provides accurate tool curves for any power from any specified base, even "saddle backs."
  • Computes near prism, over refractions and fitting distance that differs from refracted distance.

Competitive Tools

  • Optifacts knows that the industry is competitive, so we have designed tools to keep your lab competitive above and beyond the excellence of our optical calculations.
  • Account messaging automatically reminds lay out operators and lab personnel of your customers' most sensitive needs or requests.
Give your accounts what they want. You can control:
  • Thickness
  • Prism Thinning
  • Safety margins for cut-out on uncuts and edged work
  • and much, much more.
Control the above features for each material and each account with separate contols for edged, uncut and stock!

Flexibility and Power

Configure the system to fit your lab equipment. Control tool index, prism index, surface removal, ring vs. blocked prism, flex compensation, and much, much more per material.

Optional packages allow interfaces with the most advanced lab equipment available. Frame trace interfaces  allow the use of highly accurate frame tracings to insure accurate frame data to insure accurate thickness calculations.

Optifacts is aggressively pursuing interfaces with all major brands of frame trace and generator equipment as they are developed to insure the flexibility to buy the lab equipment you choose. Ask for availability.

Although modular, all of the Optifacts modules are integrated so you have less entry time and more results. Consider this:

In less than 60 seconds an operator can:

  • load a job into Job Tracking,
  • produce a printed invoice,
  • produce a priced invoice,
  • post the transaction into Accounts Receivable,
  • select the best lens blank for the job based on your lens choices,
  • decrement on-line inventory,
  • produce an extensive lab ticket for surfacing and finishing,
  • prepare interface files for all interfaced equipment,
  • flag the lenses for reordering.

The Bottom Line

  • Can reduce breakage from optical and human errors.
  • Can reduce operating costs.
  • Could turn your lab into a "specials" lab overnight.
  • Can give your lab the competitive edge you need.

Other Special Features

Split manufacturers, adds, segs and blank sizes are routine and contained on one work ticket. No manual conversion of data required for Rx entry. Seg heights and drops, mono and binocular P.D.s, pupil heights on progressives, and decentrations are all interpreted by Optifacts.
  • Matched edged thickness for cosmetics.
  • Match color on glass for cosmetics.
Automatic thickness controls for:
  • Facets
  • String / Grooves
  • Industrials
  • Glass segments
  • Polarized lenses
  • Executive bifocals and trifocals
  • Hi fit segs
Other options by account and material include:
  • prism thinning by progressive type, and bifocal and trifocal OC placement.
  • Enter finished center thickness on plus Rx's at doctor's request. Great for uncut work!
  • Abbreviated work ticket for "edge-only" Rx's.

Preloaded Lens Data Base

Features:
  • All major lens manufacturers.
  • All common styles, blank sizes, lens materials and bases.
  • Easy to edit, add, change, delete and print out.
  • Easy to learn and operate in one sitting.
  • Virtually unlimited capacity.
Benefits:
  • Easier to learn, faster throughput for operators.
  • Increased accuracy on cut-out, prism control, power and thickness

Frame Data Base

Features:
  • Allows surfacing layout and other processing information to be accurate.
  • Store frame pricing for use with Rx and stock pricing.
  • Considers all necessary information to make finishing layout and edger settings accurate.
  • Easy to edit, add, change, delete, print out.
  • Use frame trace interface programs to easily store frame data for use on uncut and "Frame to Come" jobs.
Includes these built in factors:
  • Pattern hole centering
  • Frame eye size errors corrected
  • DBL / Bridge differences for correct P.D's
  • True pattern size and box dimensions
  • Frame usage
  • Pattern circumference
  • Availabilities
Benefits:
  • More accurate finished lens thickness, cut-out information and blank size requirements.
  • No manual measurements on lenses and frames.
  • Fewer rejects due to errors in entry. Screen shows availabilities, doesn't allow invalid entries.
  • Easy to learn, faster to operate.
  • Accurate finishing layout.
  • Accurate edger settings.
  • Produces valuable frame reports.
  • Frame names for input verification
  • Pattern location and edger settings for finishing department
