We examined the possible effects of smoking on color vision: specifically, whether smokers perceive a different pattern of suprathreshold color dissimilarities from nonsmokers.
In addition, the majority of respondents were single (61%), did not have children (84%), and were nonsmokers (88%).
The key results are that smokers are impaired relative to nonsmokers.
Among reported nonsmokers, only 1.4 percent had serum cotinine >15.0 ng/ ml, the selected cut-off point for identifying smokers in their report (2).
Tobacco use was classified as nonsmoker (0) or smoker (1).
Thus, male and female smokers and nonsmokers were compared separately.
