Age-related cataract (ARC) is a leading cause of impaired vision among elderly populations. ARC is generally characterized by a gradual painless loss of vision. ARC pathology is believed to result from a combination of risk factors acting over many years, such as smoking; ultraviolet light; exposure to heavy metals, including cadmium and mercury (Hg). For many of these factors, oxidative damage or unbalance in reduced GSH concentrations may be the underlying process leading to degenerative opacities of the lens.
Over the last several decades a wide variety of studies have linked mercury exposure to various visual impairments, most notably color vision loss. Unfortunately the majority of these studies have been done overseas and mercury toxicity is not tested for when being evaluated for color vision loss.
Mercuryexposure.info was created and is maintained by consumers injured from exposure to mercury vapor and particles released by their dental amalgam fillings during placement, polishing, removal and day to day use. We are dedicated to providing accurate, up to date information on the many facets of dental mercury amalgam fillings.
