Not an expert of course and was asking for more help.
I filed and it was turned down then someone else read it and I was granted, still fighting. If I were you, I would have appeal or file again, rule says if you develop it while in service and continues to bother you with medical documentation you have a case and if you are medically required to wear contacts and I am, it's 30%, my vision is getting worst. trying to find out how to get a higher rating. Hope that helps.
