Lenses that will have two/multiple base curves very close to each other in the radiuscope are described as what?

Explanation:
When a radiuscope shows two or more base curves that are very close in value, it suggests deformation of the lens surface—warpage. This irregular pattern isn’t what you’d expect from true multi-curve designs. A toric or bitoric lens would produce distinct, clearly separated base curves corresponding to different meridians, while a spherical lens has essentially one uniform base curve around the entire lens. So this close-cluster pattern points to a warped lens, indicating surface distortion rather than a deliberate multi-curve geometry.
