Plastic is considered the most basic lens material because it is the least expensive and meets the basic quality standard for eyeglass lenses (framesdirect.com/knowledge-center/eyeglass-lens-guide).

Plastic lenses, also called CR-39, can be used for single vision, bi-focal and progressive prescriptions.
