As a matter of fact, the people who have blurred vision don't mean that they can not see things in front of them, it just means that they see a single blurry and unclear image of an object. As we know that the brain on receiving information from the eyes processes it and come up with a three-dimensional image. But, what if there is lack of muscle coordination, due to some reason. The eyes cannot focus on the same object and this leads to blurred vision. There are many reasons which can cause the blurred vision, such as alcohol, stress, and deficiency in rest and so on. All in all, as long as you see things vague and cannot focus on them, probably you have blurred vision and you need medical care.
