There are 3 types of optical anomalies:<\/p>\n<p>&nbsp;<\/p>\n<p><strong><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-32993 alignright\" src=\"https:\/\/www.drvincentqin.be\/wp-content\/uploads\/2023\/03\/1.png\" alt=\"\" width=\"237\" height=\"169\" \/><\/strong><\/p>\n<p><strong>Myopia<\/strong><\/p>\n<p>This is the most common optical anomaly. A myopic eye is one in which the eyeball is too long. The image of an object seen by a myopic eye is formed in front of the retina. Near vision is sharp, far vision is blurred.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><strong><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-32996 alignright\" src=\"https:\/\/www.drvincentqin.be\/wp-content\/uploads\/2023\/03\/2.png\" alt=\"\" width=\"237\" height=\"169\" \/><\/strong><\/p>\n<p><strong>Hyperopia<\/strong><\/p>\n<p>This is the opposite of myopia. The eyeball is not long enough. The image of an object seen by a hyperopic eye is formed behind the retina. Near and far vision is blurred.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><strong><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-32999 alignright\" src=\"https:\/\/www.drvincentqin.be\/wp-content\/uploads\/2023\/03\/3.png\" alt=\"\" width=\"237\" height=\"169\" \/><\/strong><\/p>\n<p><strong>Astigmatism<\/strong><\/p>\n<p>The cornea is curved more in one axis than in another instead of being round. It is impossible to focus images, because some lines (e.g. vertical) are sharp and others (e.g. horizontal) are blurred. The astigmatic eye therefore sees more clearly in one direction than in the other. Can be combined with myopia or hyperopia.<\/p>\n<p><strong>Presbyopia.<\/strong><\/p>\n<p>From the age of 40 onwards in all human beings, a decrease in near vision for reading. It can be combined with myopia, hyperopia or astigmatism from this age.<br \/>\nIt is a loss of elasticity of the lens due to old age. The eye is no longer able to accommodate, i.e. to make an effort to focus for close-up vision. Short-sighted people have an advantage in presbyopia because some can remove their glasses to see close up. In other cases, progressive lenses are indicated. Hypermetropes are at a disadvantage when they also become presbyopic, and will need to wear progressives.<\/p>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row full_width=&#8221;stretch_row_content&#8221; css=&#8221;.vc_custom_1665505883361{margin-bottom: -40px !important;padding-top: 6vh !important;padding-right: 6vh !important;padding-bottom: 6vh !important;padding-left: 6vh !important;background-color: #5abbed !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}&#8221;][vc_column width=&#8221;1\/6&#8243;][\/vc_column][vc_column width=&#8221;2\/3&#8243;]<div class=\"title-wrapper  basel-title-color-white basel-title-style-simple basel-title-size-extra-large text-center \"><span class=\"title-subtitle font-default\">Ophthalmologist in Brussels and Namur<\/span><div class=\"liner-continer\"> <span class=\"left-line\"><\/span> <h4 class=\"title\" >CONTACT<span class=\"title-separator\"><span><\/span><\/span><\/h4> <span class=\"right-line\"><\/span> <\/div><\/div>[vc_column_text basel_color_scheme=&#8221;light&#8221;]<\/p>\n<p style=\"text-align: center;\">You want to make an appointment?
