Whether it is normal or not, it depends on how far you are talking about. Firstly I would like to introduce what is the so called normal vision. When our eyes are kept still, the light of same height coming from some source 5 meters away travels through the curvature of lens and gets focused on retina and provides a clear and sharp image. This is the so called normal vision. If with the same condition yet the image you got is blurry, then you might have some vision problem. But as you know, there are too many people who have vision problem, such as myopia, hyperopia and astigmatism. These vision problems are very common, and you can get the vision corrected with a pair of suitable glasses. It is not a big deal. Visit your optometrist and get a pair of glasses prescribed. If you are OK with wearing contact lenses, you can try. After wearing the contact lenses, you might get the feeling that there is no vision problem at all.
