1, lack of scientific basis: Qishikang's vision correction method has not been scientifically verified, and its theoretical basis and therapeutic effect are controversial, so it is impossible to determine whether this method is really effective.
2. False advertisements: There are false advertisements in the advertisements of Qishikang vision correction products, which exaggerate its therapeutic effect and scope of application and mislead consumers. This makes it difficult for consumers to judge the real effect and quality of products.
