How to Create Conditional RX Fields
Some eye-lens products require RX details like SPH, CYL, AX, BC, or DIA. Using conditional RX fields keeps the form simple and accurate, with certain values dependent on others—for example, Cylinder options changing based on Sphere. These dependencies should update dynamically on the frontend, showing only valid choices for each lens type or variant.
