What is another word for Bi-Convex?
Pronunciation: [bˈa͡ɪkɒnvˈɛks] (IPA) 
Bi-convex is a term commonly used in optics and refers to a lens with both surfaces curved outwards, creating a convex shape on both sides. Synonyms for bi-convex include double-convex, biconvex, equiconvex, and symmetrical convex. These terms are often used interchangeably to describe lenses with this particular shape. Another synonym for bi-convex is spherically convex, as the curvature of both surfaces follows the same pattern as a sphere.
