Anyone who has to go through the feeling of looking at everything is blurry, doing everything must ask others to feel the danger of vision impairment, I used to be like that. During one watching TV, I saw the doctors talking about Alphavit, I immediately ordered this product. Using 1 box I found my eyesight improved, so I bought 2 more boxes, now I have seen much more clearly, can do everything without asking anyone. I can even hold my phone and type these words, which is something that I did not dare to think about before
