I'm a wedding photographer and I make my living with my eyes. Over the last ten years, I've had to wear readers, but my distance vision was fine. About three weeks ago, I was at a wedding, and my distance vision was off. The next day I was extremely thirsty. I drank around 160 oz. of water. Highly unusual for me. The next day I googled my symptoms, and there it was. Diabetes kept popping up, and all the signs and symptoms pointed to it. I decided I needed to see the doctor as soon as possible.
