ABSTRACT:
A system and method for determining an eyeglass/contact lens power is provided, which can determine the power of an eyeglass/contact lens that is suitable for an individual. The eyeglass/contact lens power determination system (20) according to the present invention comprises inputting means (202) for entering information on the condition of a subject's eye, means (204) for determining an optical eyeball model corresponding to the information on the eye condition entered through the inputting means (202), and means (218) for selecting a lens power for verifying the focal power of an eyeglass/contact lens worn by the subject using the optical eyeball model determined by the optical eyeball model determining means to select a lens power.
