In Lens Configuration, Base Curve Charts are listed by key fields (Material, Chart #, Manufacturer, Treatment, Add). When you highlight a chart, Rx-Universe also shows which lens styles are using it. That “styles using this chart” list is the fastest way to confirm you are editing the chart that actually impacts production.
Double-click a chart to open the grid. The values down the far-left column are sphere powers, the values across the top are cylinder powers, and each cell in the grid is a base curve target.
This is why small changes can have a big impact, a single row or diagonal adjustment can shift a large range of Rxs.
3) Creating a new Base Curve Chart
If you need a separate chart for a material or lens style, click the green plus icon to create a new chart.
Material and Chart # are required
Use a unique chart number not already defined in Rx-Universe
Rx-Universe assigns a unique color to each base curve value, which makes it easier to see how the chart transitions across Rx ranges.
After you enter initial values, right-click a cell to use the copy/replace tools. These are designed to save time when you are shifting patterns rather than typing every cell manually.
Common operations:
Copy and replace to end of line (fills a row)
Copy and replace curve to right and down (fills row and column until values change)
Copy and replace curve up staggered by one, two, or three (fills diagonally upward)
If you need to clear a section quickly, you can also delete entries by performing the same operations on a blank cell.
To avoid unintended consequences:
Identify the lens styles tied to the chart
Pick 2–3 “test” jobs that represent common Rx ranges for those styles
Make small, controlled changes, then re-run your tests
If you are unsure whether your lab should prioritize curve targets vs what is in stock, pause and review with Support before broad changes
For the full, step-by-step walkthrough (with screenshots), see our official knowledge base article in Confluence. It shows exactly where to find Base Curve Charts, how to read the grid, how to create or update a chart, and how to use the copy/replace tools to make changes quickly and consistently.
