The results of a study conducted by scientists at the American University Rutgers show that smoking excessively deprives the smoker of the possibility of distinguishing colors and causes blindness in the elderly.
To investigate this problem, the researchers brought together two groups of volunteers aged 25 to 45, according to the journal Psychiatry Research. And divide them into a group of non-smokers, and others include excessive smoking (more than one pack a day).
The results of tests and tests, indicating that smoking negatively affects the distinction of the color spectrum, that smokers distinguish red, green, blue and yellow, do not make it possible to determine the brightness of the color.
According to researcher Steven Silverstein, the loss of smokers' ability to distinguish colors is caused by the effects of tobacco smoke in the brain.
Silverstein said that cigarette smoke helps thin the brain layers responsible for image processing. "The new data indicates that nicotine and smoking damage blood vessels, retinal neurons, yellowing and inflammation of the lens, and that excessive smoking increases the risk of chronic macular degeneration of the retina, thereby preventing the person to see clearly ".
