Abstract
The concept of a new kind of pregressive addition lens was developed by using a simulation study with the ZemaxTM lens design program adopting birefringent materials as lens glass. The results of the numerical analyses revealed that the astigmatism of birefringent (calcite) progressive addition lenses could be improved on the periphery by about 6 % as compared with general standard progressive addition lenses. From these results, if an appropriate form birefringence is used in the lens manufacturing process, improvement of optical quality of the progressive addition lenses can be expected.
