Explanation

In 2007, the social security administration updated the cirteria for measuring legal blindness when using never low vision test charts with lines that can measure visual acquity between 20/100 (6/30) and 20/200 (6/60). Under the new criteria, if a person.s visual acquity is measured wit the newer charts and they can not read of the letters on the 20/100 line, they will qualify as legally blind, based on a visual acquity of 20/200 (6/60) or less.
