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.
Nearsightedness does not mean that youâre able to see things that are near really well. Nearsightedness, or myopia (or shortsightedness), actually means that seeing things at a distance is difficult for you. You may be able to read books with no problem but street signs that are far away appear blurry to you. Nearsightedness is caused by light not falling directly on your eyeâs retina but in front of it.
