The three-year completion deadline for feasibility studies is counted from the signing of the Feasibility Cost Sharing Agreement (FCSA), which initiates the feasibility phase, until the Chief of Engineers signs the Chiefâs Report.
Legal blindness relates to the best corrected vision after an eyeglass prescription is determined. You cannot look at the numbers on your eyeglass prescription to determine this. If the best you can do on an eye chart, with the best eyeglass correction, is 20/200, that is legal blindness in most states in the usa.
A person is considered legally blind if his or her corrected vision is no better than 20/200, meaning seeing at twenty feet what others see at two hundred feet or having peripheral fields (side vision) of no more than 20 degrees diameter or 10 degrees radius.
