What the colors mean
Color tracks physical thickness across each lens: thicker areas become progressively redder. The model’s shape and edge profile update together.

Adjust the measurements to compare how frame choice and index affect the result.
Demonstration estimate only. This uses a simplified lens-sag model with a 1.5 mm minimum thickness and equal monocular PDs. Actual finished thickness varies with base curve, aspheric or atoric design, bevel placement, frame shape, safety minimums, and lab surfacing.
