Eyes are strange

Well I had my eye exam yesterday. Rather interesting when you have to run to your car with your head under your coat and try to find your sunglasses. I had drops put in to open the iris and well for the rest of the day my eyes were extremely sensitive to light. Must have been an strange sight for people to see someone running with a jacket over their head. It took about 15 hours for my eyesight to get back to normal. I could not focus on anything and wearing my glasses was useless.
