Smoking affects the health of large numbers of people and nearly 8 million deaths each year are related to smoking in the world. The harm of smoking is obvious and widely known and it can have direct and negative effects on the eyes and vision. The news of the World Health Organization (WHO) claims that the risk of specific eye diseases and permanent vision loss will be raised due to smoking. To make the public realize the dangers of smoking more comprehensively, the WHO therefore designated May 31st as World No Tobacco Day.
