A new study from Rutgers University in the United States once again sounded the alarm for these obsessives. Researchers published a study in the Journal of Psychiatry Research that smoking not only affects the cardiovascular system, but also impairs vision. More than 20 cigarettes a day, smokers' ability to discern chromatic aberration and contrast is significantly reduced.
The new study involved more than 130 adult volunteers between the ages of 25 and 45, 63 of whom were smokers, smoking more than 20 cigarettes a day, and more than 70 were basically non-smokers. The number of smoking in the group is less than 15. Standard eye chart measurements showed that these volunteers had normal vision or corrected vision.
The researchers tested volunteers' ability to discern contrast (shadow nuances) and color. They found that compared with non-smokers, these over-smokers had significantly reduced ability to distinguish between contrast and color. They had more or less symptoms of color blindness or weakness, and their red-green and blue-yellow vision were flawed.
Researchers have pointed out that past studies have shown that long-term smoking can lead to a multiplication of risk of age-related macular degeneration, and their new research suggests that excessive smoking or prolonged exposure to harmful compounds in tobacco can seriously affect smokers' ability to distinguish colors. And the ability to contrast, may lead to the loss of overall color vision, the overall harm of smoking to vision can not be ignored.
The new study did not give a clear physiological explanation for the results, but the researchers pointed out that it may be related to the destruction of blood vessels and neurons in the retina by harmful substances in tobacco such as nicotine. At the same time, they also suggested whether smoking and smoking levels are an important consideration in future visual impairment studies.
