If the character encoding for a web page is chosen appropriately, then HTML character references are usually only required for markup delimiting characters as mentioned above, and for a few special characters (or none at all if a native Unicode encoding like UTF-8 is used).
Far-sightedness, also known as long-sightedness and hyperopia, is a condition of the eye in which light is focused behind, instead of on, the retina. This causes close objects to be blurry, while far objects may appear normal. As the condition worsens, objects at all distances may be blurred.
farsightedness; the ability to see distant objects but not close ones; relative length of the eye is too short, the cornea is too flat, or the lens has too little refractive power; focal point is too far from the lens, and the image is focused behind the retina; corrected by convex lens that causes light rays to converge as they approach the eye.
