| Summary: | 碩士 === 逢甲大學 === 資訊電機工程碩士在職專班 === 100 === The purpose of this study is to use aspheric lens to Design the lens which prevent and control myopia by conforming to the Diopter of center and edge of retina. This design is concentrating on the customization of spectacles for myopic patients to increase clear edge image of retina and prevent the increasing Diopter. Using human-eye structure can simulate four Different fields of view of human-eye which are 0°, 10°, 15°, 20°. Let object rays of each angle focus on retina and we optimizes myopic lens to incur clear images inside 20°. Suppose that these edge images of retina are clear, the main purpose for preventing myopia is achieved as the axial length of eye would not increase.
Myopic lens is chosen from the range between -1.00D to -4.50D, which is further divided into four groups. Each group serves as multi-configuration optimizing Design suitable for Different the axial length of eye. MTF can also reach planned performance. Normally, fifteen optics lenses are needed to correct myopia, after multi-configuration optimization only four optics lenses are necessary.
