Yes, I think it really works as treatment to blurry vision. Blurry vision is very common that a large amount of people might experience sometimes. Causes of blurry vision range from simple eye dryness to complicated systemic disease. I think the first thing you to do is to find out what caused your blurry vision. If it is some common vision problem, like myopia, hyperopia or astigmatism, you can get your vision corrected by a pair of glasses prescribed. If you insist to try acupuncture, I think it works. According to traditional Chinese medical theory, the acupuncture can break through the blockage of energy of human body to get the blood circulation promoted and so illness is cured or bettered. So if your blurry vision is caused by some complicated disease, acupuncture could help anyway to some extent. But just as I said, finding out the root can help you get proper treatment and healed. Good luck!
