A recent study by Sophia Wang, PhD, from the Department of Ophthalmology, University of California San Francisco School of Medicine has shown an increase in the incidence of Glaucoma in people who are taking Calcium supplements, and also those who take Iron supplements. The study also found that people who take both supplements are at the highest risk. The study also reported that there seemed to be a protective mechanism by adding a Magnesium supplement.
Further investigations into the mechanism of action of these supplements will be required, to fully understand why they have the effects they do.
Like the post on Glucosamine, you should be aware that taking these supplements may increase the risk of glaucoma, so regular eye examinations are important.
