Abstract
In this paper, the bicubic spline interpolation and high-order polynomial methods were used to optimize the edge thickness of negative blended lenticular lens for patients having high myopia and astigmatism, which are large thickness and weight. For -8D lens with -2D cylinder in 180° axis, based on the setting a valid optical area, the outside area of the blended lenticular lens were designed . The optimized lenses were processed by CNC machine, measured and analyzed. The central optical area obtained via bicubic spline interpolation method is 48.98% greater than high-order polynomial method. The maximum thickness obtained using high polynomial method is 0.62% less than that obtained via bicubic spline interpolation method, which is 17.40% less than the original surface in 180° axis. The edge thickness under high polynomial method is 9.60% larger than bicubic spline interpolation method, which is 71.57% less than the original surface in 180° axis. Therefore, it was concluded that the bicubic spline interpolation method meets the requirements of the wearers. These methods are also suitable for designing other types of optical components.
