Outline of Final Research Achievements

Humans obtain visual information from a picture which is made on the retina (screen) by adjusting the crystalline lens with a ciliary body (muscle). When a clear picture is not made on the retina due to ametropia caused by several factors, humans have myopia, hyperopia, presbyopia, or astigmatism.
In this research, a method to make a de-focus picture (blurred image) on the display of a smart phone or a personal computer was developed in order to give a clear picture to a person taking myopia, hyperopia, presbyopia, or astigmatism without anastigmatic lens.
