Wave's single vision designs are the foundation for all of our designs. First and foremost to success for any of our designs is proper fit. All Wave designs begin with our Multiple Aspheric Design concept. Each lens design consist of multiple curves as small as 10 microns. Compare the resulting 100s of curves to other labs 3, 4, 5 or 6 curves and you appreciate the difference Wave makes. Even a standard aspheric lens is simple compared to a Wave design.
All of Wave design controls are available with single vision design except the multifocal controls. But once you do enter additive power, the lens does become a multifocal. Likewise, if you enter astigmatism, the resultant power is spherical equivalent and the design remains 'spherical'. But as soon as you enter an astigmatic over refraction the design becomes a front surface toric. But keep in mind that our thinner lens capability often lets you avoid moving up to a toric design.
