No there is no medication that can stop or reverse or prevent cataracts. The claims made by this company are bogus. There have been drops sold to prevent, stop, reverse cataracts for over a century. Their claims are totally bogus and misstate the studies that include in their advertising. What does cause cataracts: heavy drinking, smoking, nicotine, obesity, diabetes, steroids, heavy sun exposure, bad diets, trauma to the eye these can all be modified by lifestyle changes. Getting older is something none of us can do anything about.
