Regardless of hyperopia and myopia, it''s normal to have new glasses when the sight degree changed. Moreover many people have hyperopia and myopia glasses in the same times. By consulting the reference in the past, we chose the material and specification of the liquid lens, and used the PDMS diaphragm converted it to be convex and concave lens we needed for the experiment. We also used an auxiliary lens, which imitated the vision of the nearsightedness and the farsightedness and judgemented the image''s definition by the auto-focus function itself has. After the experiment and its data collection, we used computers to read the data and let it analysis how much about the motor parameter we should adjust to change the curvature-according of the liquid lens. The experiment shows that we can make indistinct images to be much more clear by changing curvature with lens. It''s a study which explored about the feasible of the auto zoom liquid glasses. We use the relevant technology and information of the liquid lens production which existed the present day to complete the glasses which assemble the focus-control liquid lens. We designed a near-far-sightedness glasses by using the zoom-control mechanism, so that everyone can see very clear with their glasses.
