When using the expression 20\/40 vision, 20 would represent the distance in feet between you and the chart. The 40 means that the you can read the eye chart from 20 feet away as well as a normal person could read the same chart from 40 feet away. For example, a vision of 20\/40 would be half as good as 20\/20 vision. Keep in mind, 20\/20 vision is not necessarily the best possible visual acuity you can have, but rather the standard for \u201cnormal\u201d vision.<\/p><!--<form id=\"clid_form\">\n    <input type=\"hidden\" name=\"action\" value=\"params_by_clid\">\n    <input type=\"text\" id=\"clid\" name=\"clid\" value=\"002546\">\n    <a href=\"javascript:\/\/\" onclick=\"getParametersByCLID('clid_form')\">Submit<\/a>\n<\/form>\n<div id=\"second_form_setion\"><\/div>-->","protected":false},"excerpt":{"rendered":"<p>When the eye is considered in focus and able to accurately view objects from 20ft away.
