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.
Farsighted is simply the opposite. Farsightedness or hypermetropia or hyperopia is a defect of vision in which closer objects appear to be blurred. It occurs because the eyeball is too short, the lens has incorrect curvature or the cornea is flat.oth are refractive conditions, meaning that they are problems related to how the light is focused as it enters the eye. Ideally, as light enters the eye, without any additional effort, the light would be perfectly focused onto the inside lining of the eye which detects the light, called the retina.
