The best (and most well-paid) pitchers in baseball tend to be those with an excellent command of the curveball, able to throw at high velocity while also ensuring that the ball traces the arc of a curve with the utmost precision. Scleral lens design also relies on precise control of the curve.

As in baseball, success stems from a solid foundation in the principles of physics. But scleral lens design is quite a bit simpler—just a matter of adjusting curves and manipulating distances to achieve the desired effects of sagittal depth. This article provides an overview of key facts that can help you master scleral contact lens fitting

Scleral Design 101 There are three main components to scleral lens design: the optic zone, the transition zone over the limbus and the landing zone on the sclera. Each zone is comprised of one or more curvatures, each of which has defined diameters. The shape of ...
