Is there evidence that eye exercise helps with myopia prevention or the slowing of its progression ?

According to this article (http://www.allaboutvision.com/buysmart/see_clearly.htm), there is little or no scientific evidence that shows a relationship between eye exercises and the slowing or reversing of myopia. The article noted that exercises are unable to help change the shape of the eyeball. Therefore, is unlikely that it will help in correcting myopia.
