What is it about?
In this paper, we report the effects of chronic heavy smoking on visual processing, specifically assessed by color discrimination (chromatic processing). Cigarette smoke is probably the most significant source of exposure to toxic chemicals for humans, involving health-damaging components such as nicotine. Since there may exist nicotinic receptors on these streams, how it will interact and affect spatial vision?

Why is it important?
Whereas there is a lack of studies involving smoking effects on color vision, this highlights the importance of a rigorous testing procedure that measures spatial vision by chromatic processing. An attempt to fill the gap in studies that assess visual changes caused by smoking is an important step to promote strategies of smoking cessation, since vision mayhap the gateway to cognition. The paper should be of interest to readers in the areas of visual neuroscience, psychology, cognitive and behavioral neuroscience, physiology and psychiatry
Perspectives
Since we did not observe changes in ophthalmoscopy, optic coherence tomography, photorefraction, nor the participants presented conditions that could be intervenient variables (depression, elevated anxiety and other neuropsychiatric disorders), we could, in a way, reduce the results to the effects of the use of the cigarette. More specifically, we hope this is the first step in understanding the existing effects of cigarette smoke and cigarette compounds, since it is very difficult to isolate one or two mechanisms and explain based on that. We assume that cigarette compounds (involving smoke compounds such as toluene) may affect visual spatial processing.
