摘要：
The aim of this research is to design a myopic ophthalmic lens by using ZEMAX optical design software. The myopic ophthalmic lens is designed by integrating the effects of myopic eyes. The first design started from adjusting the design of purely using lens making formula by ZEMAX's simulation, named “eyeglass 1” of -0.93D myopic ophthalmic lens for -1D myopia . It then shows that the lighter power of the myopic ophthalmic lens is more suitable for the -1D myopia. This verifies that spectacle design should take into account the effects combined effects of the ophthalmic lens and the eye. If the lens is viewed to match the three configurations named far, middle, and near view points according to the human eye structure, an aspheric surface is introduced to the lens “named eyeglass 2”, which gives more freedom to correct the aberrations. At the end of this study, we show that the choice of “far distance” gives an even more suitable ophthalmic lens for myopia, and this is shown by “eyeglass 3 & 4”. The MTF values show that it is about 0.3 when spatial frequency is 83lp/mm “20/20 vision”.
