It is usually because the eye is too long, which makes images come into focus in front of the retina. It is a hereditary defect. Myopia magna is when the condition exceeds 6 dioptres. In these cases, patients are at greater risk of retinal problems.<\/li>\n<li><strong>Hypermetropia, or long-sightedness<\/strong>: In this case, images come into focus behind the retina, usually because the eye is too short. If the refractive error is not too great, the eye can correct it with help from a lens, so it can be symptomless (especially in children). Initially it causes difficulties seeing things close up (reading, using the computer etc.) and can cause headaches when continuous effort is required to see things that are close by. When levels of refractive error are high, or when presbyopia appears, distant objects will also appear blurred.<\/li>\n<li><strong>Astigmatism<\/strong><em>: <\/em>In this case, the image is doubled in two focus points, which are shown in different positions. Depending on how separated they are, it causes objects to look fuzzier in a certain direction (like a watercolour with the ink running in one direction) and the image becomes distorted. Astigmatism affects objects at all distances. It is caused by an asymmetry in the cornea, which is more curved on one axis than the other (like a rugby ball). Sometimes it can be associated with corneal degeneration.<\/li>\n<li><strong>Presbyopia<\/strong> (or tired eyesight): This condition is a natural loss of lens focus related to ageing, which makes it difficult to see from far away, and especially up close. Patients notice they have to extend their arm to read. Presbyopia increases with age, from about 40 to 60 years old, but progression will stop when the eye has lost all ability to focus.<\/li>\n<\/ul>\n[\/vc_column_text][\/vc_column_inner][vc_column_inner width=&#8221;1\/3&#8243;]<div class=\"vcex-spacing wpex-w-100 wpex-clear\" style=\"height:15px;\"><\/div>[vc_single_image image=&#8221;1604&#8243; alignment=&#8221;center&#8221; onclick=&#8221;img_link_large&#8221;]<div class=\"vcex-spacing wpex-w-100 wpex-clear\" style=\"height:15px;\"><\/div>[vc_column_text]\n<blockquote><p>Some refractive errors can be detected at an early age.<\/p><\/blockquote>\n[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_tta_section][vc_tta_section title=&#8221;Evaluation&#8221; tab_id=&#8221;1508258154839-35b76ff9-306eec28-b43141f5-a9a1&#8243;]<div class=\"vcex-spacing wpex-w-100 wpex-clear\"><\/div>[vc_row_inner][vc_column_inner width=&#8221;2\/3&#8243;]<h3 class=\"vcex-heading vcex-heading-plain vcex-module wpex-heading wpex-text-2xl\"><span class=\"vcex-heading-inner wpex-inline-block\">Evaluation<\/span><\/h3><div class=\"vcex-spacing wpex-w-100 wpex-clear\"><\/div>[vc_column_text]<strong>Objective refraction test<\/strong>: Two methods are used, the retinoscope and the auto refractometer.

What happens is that the brain adapts to any blurry vision by believing that it looks fine, when this is not the case. Once you can see clearly, the brain will not accept vision that is worse, which &#8220;forces&#8221; it to correct the error.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Can presbyopia be prevented?&#8221; tab_id=&#8221;1508266907907-dd75489a-4347ec28-b43141f5-a9a1&#8243;][vc_column_text]No. It is a natural and physiological process that takes place in the eye, like other similar processes in the human body (such as the menopause). There is no method or diet that can delay it.[\/vc_column_text][\/vc_tta_section][\/vc_tta_accordion][\/vc_column][\/vc_row][vc_row][vc_column]<style>.vcex-heading.vcex_69e20d2711731{color:#ffffff;}<\/style><h2 class=\"vcex-heading vcex-heading-plain vcex-module wpex-heading wpex-text-2xl vc_custom_1577991403204 vcex_69e20d2711731\"><span class=\"vcex-heading-inner wpex-inline-block\">Related entries<\/span><\/h2>[\/vc_column][\/vc_row][vc_row][vc_column]<div class=\"vcex-module vcex-post-type-grid-wrap wpex-clr\"><div class=\"wpex-row vcex-post-type-grid entries wpex-clr\"><div class=\"vcex-post-type-entry vcex-grid-item wpex-clr col span_1_of_2 col-1 entry post-2030 type-post has-media cat-152 cat-69 post_tag-190 post_tag-191 post_tag-157 post_tag-192 post_tag-189 post_format-39 translation_priority-230\"><div class=\"vcex-post-type-entry-inner entry-inner wpex-first-mt-0 wpex-last-mb-0 wpex-clr\"><div class=\"vcex-post-type-entry-media entry-media wpex-relative\"><div class=\"vcex-video-wrap\"><div class=\"wpex-responsive-media\"><iframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/gUmWUb0Qbt8\" frameborder=\"0\"><\/iframe><\/div><\/div><\/div><div class=\"vcex-post-type-entry-details entry-details wpex-bordered wpex-first-mt-0 wpex-last-mb-0 wpex-clr\"><h2 class=\"vcex-post-type-entry-title entry-title wpex-mb-5\"><a href=\"https:\/\/inofinstitut.com\/en\/is-it-important-to-check-visual-acuity-in-children\/\">Is it important to check visual acuity in children?<\/a><\/h2 ><div class=\"vcex-post-type-entry-excerpt entry-excerpt wpex-my-15 wpex-text-pretty wpex-last-mb-0 wpex-clr\"><p>When examining a child's eyesight, visual acuity entails measuring the smallest size of an object that can be seen with&hellip;<\/p><\/div><div class=\"vcex-post-type-entry-readmore-wrap entry-readmore-wrap wpex-my-15 wpex-clr\"><a href=\"https:\/\/inofinstitut.com\/en\/is-it-important-to-check-visual-acuity-in-children\/\" class=\"entry-readmore theme-button\" aria-label=\"Read more about Is it important to check visual acuity in children?\">Read more<\/a><\/div><\/div><\/div><\/div><\/div><\/div>[\/vc_column][\/vc_row]\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row full_width=&#8221;stretch_row&#8221;
