Bad eyesight contacts?

If you look at official definitons it is considered pretty mild. You have to start hitting -5/-6 before its considered bad at all. To decide if your eyesight is terrible consider what you can do without glasses/contacts. For example can you get dressed /showered easily? Can you find a door? Just how helpless are you without glasses? My guess is that your glasses help but you can function reasonably well without them if you aren't reading signs. Your dependency on your glasses tells you just how bad your eyesight is really.
