Effect of the AST Chiro Method on Visual acuity of Younger age

In the previous paper we reported that AST treatment improved visual acuity in many cases. This time, in order to investigate the effect of patients' memory on improvement of the visual acuity, we used eye measurement cards instead of a general eye chart. In this investigation, we found that the effect of the memory on the improvement of visual acuity by means of the measurement chart can be ignored when we use the global standard inspection method. We also investigated the effect of the AST Chiro Method on visual improvement for young patients. Remarkable effect on the AST Method on young patients of the visual acuity level under 0.7 has been observed and the level recovered up to over 0.7.
