Abstract

Bicurvoconic lenses. Constant of: a conical surface that has a convexo aspect (if projected outward) or concave (if projected inside) and a bicurve surface has a double aspect; consist of two tetons (of lenticular curvature), convexos, situated on each side of the focal axis, that form a hondonade in the center (or vertice bicurvoconcavo central); or in lenticular concavidades located on each side of the focal axis and united by the center or focal axis, which form a convexity (or vertice bicurvoconvexo central) in the center; they can be: bicurvobiconvexa-convexoconica (or viceversa), bicurvobiconvexa-concavoconica (or viceversa), bicurvobiconcava-convexoconica (or viceversa), bicurvobiconcava-concavoconica (or viceversa).
