The health of healthcare workers may affect patient safety in various ways. Accurate vision is necessary for examining patients, reading medication packages, reviewing diagnostic films…etc

“Human populations experience widespread low level exposure to organometallic methylmercury compounds through consumption of fish and other seafood. At higher levels, methylmercury compounds specifically target nervous systems, and among the many effects of their exposure are visual disturbances, including blindness, which previously were thought to be due to methylmercury-induced damage to the visual cortex”
