摘　　要：提出一种设计和优化渐进多焦点眼用镜片方法。通过环曲面方程计算面型矢高,与使用球面方程设计渐进多焦点眼用镜片的方法相比,采用环曲面方程设计可以分别控制镜片在x方向和y方向的曲率,这种优化方法可以有效降低镜片的像散。分别采用球面方程和环曲面方程两种方法设计镜片,其镜片参数相同。经过加工得到样品并检测,结果表明,两种方法设计的渐进多焦点眼用镜片加光度数(ADD)基本一致。与球面方程设计相比,使用环曲面方程设计的镜片,镜片左侧像散大于1.5 D区域的宽度减小1.7 mm,镜片右侧像散大于1.5 D的区域的宽度同时减小为0,视近区散光小于0.5 D的宽度增加3.6 mm。因此,采用环曲面方程的设计方法可以有效减小渐进多焦点眼用镜片大像散区的范围,同时增大视近区可视范围。A method for designing and optimizing progressive addition lenses(PALs)was proposed.The vector height of surface was calculated by the toric equation.Compared with the lens designed by the spherical equation,the curvature of the lens in x direction and y direction can be separately controlled.The optimization method can effectively reduce the astigmatism of the lens.Spherical and toric equations were used to design the lenses respectively,with the same lens parameters.Then lenses processing was performed,and the samples were obtained and tested.The results show that the addition power(ADD)of the PALs designed by the two methods is basically the same.The width of the area with astigmatism greater than 1.50 D on the left side of the lens designed by the toric equation is reduced by 1.70 mm.And the one on the right side is reduced to 0 as well.The width of the near vision zone with astigmatism less than 0.50 D is increased by 3.60 mm.Therefore,the design method by using the toric equation can effectively reduce the range of high astigmatism of the PALs and expand the wide range of the near zone visible area of the PALs simutaneously.
