What the others say. If your vision is that bad, there's no way you can forget your glasses because you just CAN'T see. Everything is blurry.
That being said, you CAN'T see so there is a possibility that you can't find your glasses where you last left them. If you're in a hurry, then you have no choice but to stop searching, run for the door, and pray that your natural vision is enough to carry you through the day.
