I know this is a little off the subject but...

It's known that mercury causes changes in eye-fluid pressure and can cause Myopia (near-sightedness - about 90%) and hyperopia (far-sightedness - about 10%).

My business partner (Laura) just began exploring the relationship between the time she had 8 fillings put in during one visit to the Dentist and her near-sightedness. She's pretty sure that her eyes went bad very quickly the year immediately after the 8 fillings were inserted. We just have to verify the dates.
