They cause blurred vision as they can also cause pressure in the had and jaw because they are in the sinuses and the bags where the tears come out near the eye, and the sinuses are not only near the nose but between the eyebrows also- sorry don’t know how to explain in English but I am sure u understand. So they do that blurred vision because of the pressure on the muscles of the eyes! And yes I take fresh grounded cloves 2 tsp and Wormwood tincture ( because I have no plant) before the enema, and inhalations! The blurred eye vision should disappear after some days of enemas and inhalations!
