New studies suggest that individuals born after 1950 have a lower risk for developing Age Related Macular Degeneration. The study suggested that childhood exposure to contaminants in the environment such as home heating with wood or coal increased the risk in previous generations. However, cigarette smoking is still an important risk factor in the development of macular degeneration.  Even if you are a non-smoker, it is important to have your eyes checked on a regular basis by an eye care professional.
