can sinuses cause blurry vision
Usually, the infection starts from one side of the maxillary sinus. It can spread through the other sinuses when not treated immediately. Clogged nose can also contribute to the pressure-like pain that he feels behind the nose. The pain around the eyes and the pressure from the cheeks causes blurred vision. When both sides of the maxillary sinus have infection, there is a tendency that vision from both eyes will also become blurry.
