Sometimes an astigmatism can result from an irregular shaped lens inside the eye. Astigmatism is quite common and frequently occurs along with nearsightedness and farsightedness. It is usually in both eyes but may be found just in one eye.<\/p><p>Like other visual conditions, astigmatism is not necessarily a fixed entity. In a study on musicians around symphony season, researchers noted that the musicians held their eyes and head in a tilted posture for long periods of time. Corneal changes occurred seasonally in a high percentage of the musicians, resulting in astigmatism. The researchers attributed these changes to the fact that the musicians&#8217; eyes tilted to adapt to their body distortion to try to maintain balance, causing the chronic straining of some eye muscles and relaxing of others. There was a near 100% correlation between the instruments played, the corresponding posture necessary to play the instruments, and the predicted astigmatism. This is an example of &#8220;function affecting structure.&#8221;<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-a5475f5 e-con-full e-flex cmsmasters-block-default e-con e-parent\" data-id=\"a5475f5\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-41f69b5 e-n-tabs-mobile cmsmasters-block-default cmsmasters-sticky-default elementor-widget elementor-widget-n-tabs\" data-id=\"41f69b5\" data-element_type=\"widget\" data-settings=\"{&quot;tabs_justify_horizontal&quot;:&quot;start&quot;,&quot;horizontal_scroll&quot;:&quot;disable&quot;}\" data-widget_type=\"nested-tabs.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"e-n-tabs\" data-widget-number=\"69167541\" aria-label=\"Tabs.

Much can be done to maintain healthy vision, however, through diet, regular exercise (including daily eye exercises), and targeted supplementation. These can significantly help reduce the risk of future eye disease.<\/p><p>Nutritional supplements such as lutein, astaxanthin, or vitamin D3, may be of value if the astigmatism is combined with retinal weakness involving macular pigment,<sup>1<\/sup>, <sup>2<\/sup>\u00a0photoreceptors, or other eye conditions.<\/p><p>Protect your eyes from the damaging effect of blue light and UV light from the sun.<sup>3<\/sup><\/p><p>Some research suggests that natural light exposure may counter-balance too much indoor\/close up work causing strain on the eyes. Even on an overcast day, exposure to natural light for 2\u20133 hours may be helpful.<\/p><p>Manage chronic stress. Research has shown that long-term tension contributes to serious disease, which factors in to the causes of eye conditions.<\/p><p>Develop a regular exercise routine. A minimum of 20\u201330 minutes of vigorous walking, swimming, etc. five days a week, for example, is excellent for eye and overall health.<\/p><p>Computer users.
