The in-house production of Single Vision lenses is obviously not a cost effective exercise. However, in the “surfaced” category, beyond the normal “stock” ranges, it becomes viable. Moreover, when a high-powered single vision lens is cast in Aspheric, Smart Shades and ARC, it certainly becomes profitable.

The multi focal range has two options in CFL 18 mm segment height and the Short Corridor 16 mm option. In practice, it has been found that the short corridor is seldom used and the CFL fulfils 95% of prescription needs.

Flattop molds come in an aspheric design.

The casting cost of all lenses is exactly the same regardless of the design, multi or single vision.
