The disclosed optical lens assemblies may include a structural support element, a deformable element coupled to the structural support element, and a deformable medium positioned between the deformable element and the structural support element. The deformable element may include a base element that, when deformed, alters an optical property of the optical lens assembly. The deformable element may have a non-uniform stiffness. Related methods of fabricating an optical lens assembly are also disclosed.
