  Significance: A method is needed to quickly determine the Minimum Blank Size (MBS) of spectacle lens for the chosen frame. Selecting the MBS is important in making high quality eyeglasses with appropriately thin centers and edge thicknesses, while maintaining light weight, cost effectiveness, and time efficiency. Using MBS can help make the decision whether to use an uncut lens blank from commercially available stock or to have the surfaced lens specially ordered from a lab. Purpose: This article introduces a new chart for instantaneously, easily and accurately determining the MBS for a specific frame and will help select a suitable blank lens and therefore control the quality, cost and turnaround time of a pair of eyeglasses. Methods: The new chart was designed with serial concentric circles matching the com.. View More»
