Blurry vision is the loss of sharpness of eyesight, making objects appear out of focus and hazy. Acupuncture is popular in China, actually in ancient China, It's the oldest, broad and profound treatment option in China. The traditional Chinese doctor speaks high of acupuncture because it seems to be useful for almost all diseases which don't need a surgery to solute. Thus, acupuncture works for blurry vision indeed. But it must spend a long time healing them. Also, acupuncture can help with blood circles and nerves. Blurry vision sometimes because of pressure in blood and nerves in brain become fatigue. So acupuncture points around heads and hands do work. I must emphasis it's really a long recovery time, you must afford any changes and overcome depress in mind.
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!
