One of the options was some sort of implant that would stop tears from leaving my eyes or something. The most popular was indeed an eye drop, but the doctor said it's expensive because, surprise surprise, the company that sells it has a monopoly on it. I couldn't find the price, so it must be high, and I try to avoid contributing to corporate coffers where I can anyway. Fortunately, I was assured that my eyesight wouldn't worsen, just my discomfort: "like having a clear windshield and faulty wipers," he said. In point of fact, I have perfect vision.
Also, "The only thing that stops a bad guy with a chaos emerald is a good guy with a chaos emerald! You'll have to pry mine from my cold, gloved hands!"
