If you are nearsighted what is wrong with your eyes?
Nearsightedness, or myopia, is a common refractive error where distant objects appear blurry. It occurs when the eyeball is too long or the cornea is too curved, causing light to focus in front of the retina instead of directly on it. This can be corrected with eyeglasses, contact lenses, or refractive surgery.

What is the definition of farsighted and nearsighted?
Hyperopia, also known as farsightedness, longsightedness or hypermetropia, is a defect of vision caused by an imperfection in the eye (often when the eyeball is too short or when the lens cannot become round enough), causing inability to focus on near objects, and in extreme cases causing a sufferer to be unable to focus on objects at any distance. As an object moves toward the eye, the eye must increase its power to keep the image in focus on the retina. If the power of the cornea and lens is insufficient, as in hyperopia, the image will appear blurred. Myopia also called near- or short-sightedness, is a refractive defect of the eye in which collimated light produces image focus in front of the retina when accommodation is relaxed. Those with myopia see nearby objects clearly but distant objects appear blurred. With myopia, the eyeball is too long, or the cornea is too steep, so images are focused in the vitreous inside the eye rather than on the retina at the back of the eye. The opposite defect of myopia is hyperopia or "farsightedness" or "long-sightedness" - this is where the cornea is too flat or the eye is too short. But someone can be both far-sighted and near-sighted.
What does 475 in right eye and 400 in left eye mean?
That depends if it has a minus sign or a plus sign in front of the numbers. The appropriate notation would be either -4.75 OD and -4.00 OS; or +4.75 OD and +4.00 OS. The sign in front makes all the difference in the world to completely answer this question. Minus sign means you are near sighted and everything in the distance is blurry without glasses or contact lenses. Plus sign means you are farsighted and would have greater difficulties reading books.
