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.
After visiting another eyeglass store, it seems that in order for them to make you a pair of prescription glasses, they must have either your old glasses so that they can read the prescription from them (using a special machine), or a written prescription with an eye doctor's signature. don't know what the law is, but the wrong prescription can certainly cause eyestrain at a minimum, and maybe damage at worst. Even if the law doesn't require it, I sure wouldn't want to get sued by giving you glasses that aren't exactly what you need.
