I have perfect vision in one eye and very poor vision in the other. While it's possible for me to drive without my glasses, I don't consider it safe. With one eye I can read signs, see pedestrians, cars, etc; but I find that the accuracy of my depth perception suffers. I estimate speed and distances with less precision. Try catching a baseball with one eye covered. It's possible but a lot harder.
