While excessive smoking has been joined to varied health problems, as well as cardiovascular disease and cancer, a brand new study has warned that smoking over 20 cigarettes a day will cause blindness. The study from Rutgers University noted that chronic tobacco smoking can have harmful effects on “spatial and color vision”.
The findings, published within the journal Psychiatry Research, noted vital changes within the smokers’ red-green and blue-yellow color vision. This implies that overwhelming substances with toxin chemicals, like those in cigarettes, could cause overall color vision loss. Serious smokers even have reduced the flexibility to discriminate contrasts and hues compared with non-smokers.
“Our results indicate excessive use of cigarettes, or chronic exposure to their compounds, affects visual discrimination, supporting the existence of overall deficits in the visual process with tobacco addiction,” aforementioned Steven Silverstein from the Rutgers’s Behavioral Health Care.
“Cigarette smoke consists of numerous compounds that are harmful, and it's been joined to a discount within the thickness of layers within the brain, and to brain lesions, involving areas like the frontal lobe, that plays a role in voluntary movement and management of thinking, and a decrease in activity within the area of the brain that processes vision,” he said.
For the study, the team looked at 71 healthy people who smoked less than fifteen cigarettes in their entire lives and sixty-three folks, who smoked over 20 cigarettes daily. The participants were within the 25-45 year group. The study’s findings showed noticeable changes within the red-green and blue-yellow color vision of serious smokers.
Previous studies had also pointed to long-term smoking as doubling the risk for age-related macular degeneration and as a factor causing lens yellowing and inflammation.
