Double Vision
It is another common symptom people complain about when suffering from cataract. Due to the protein buildup, when light passes through the lens, it gets scattered and get focused on two or more points on the retina which creates a dual image. A double vision is a condition in which the person is sees two images of a single object and both the images are distant from one another. When the cataract is at early stages of development, patient might not be able to see it clearly, but as the cataract progress seeing things clearly becomes a problem.
