Myopia is a weakness of the eye. In a short-sighted eye, the focal point (the point where the light rays meet again \u2013 i.e. where the image is formed) is in front of the retina. In a normal eye, this focal point would lie directly on the retina and thus produce sharp vision. The result is an aberration that makes nearby objects appear sharper than those further away. Hence the term short-sightedness. Short-sightedness is determined and identified by an eye examination (refraction) with an optician or ophthalmologist. It is specified in dioptres (unit of measurement for refractive power). On your spectacle prescription, you will find information about myopia under the abbreviation: sph (sphere). This value is negative for short-sighted spectacle wearers. CAUSES OF MYOPIA<\/strong> Axis myopia <\/strong>The eyeball is too long. As the image is focused in front of the retina and then dispersed, vision is blurred. Refractive myopia <\/strong>It is also possible that the refractive power of the lens system of the eye (cornea, lens) is too strong. This then causes the image to appear in front of the retina, as in axial myopia.<\/p>\n

Long-sightedness (or hyperopia) is similar to myopia in that it is a weakness of the eye. In a long-sighted eye, however, the focal point lies behind the retina, so that in the relaxed state of the eye everything looks blurred. The eye can compensate for this to a certain extent by tensing the lens in the eye. Just like myopia, there are two different causes: Axis hyperopia <\/strong>The eyeball is too short, therefore the light meets behind the retina and creates a blurred image (the opposite to myopia) Refractive hyperopia <\/strong>In rare cases, the refractive power of the eye\u2019s lens system is too weak (again in contrast to myopia).<\/p>

Astigmatism is a deformation of the cornea. In contrast to myopia and hyperopia, the length or shortness of the eyeball is not relevant here. The curvature of the cornea is not uniform, but has a dent in it. As a result, the light cannot be refracted properly and does not meet on the retina to form a point, but rather a rod shape. \u201cAstigmatism\u201d is derived from the words \u201cA\u201d for \u201cnot\u201d and \u201cstigma\u201d for \u201cpoint\u201d. The translation would then be: \u201cnot at one point\u201d.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
