Although most people associate smoking with lung cancer and heart disease, few are aware of the impact of smoking on ocular health. Studies have suggested a better knowledge of this association might promote higher quit rates, particularly in teenagers. The purpose of our study was to determine the knowledge of teenagers about the effects of smoking on ocular health and the fear associated with several tobacco-related health conditions.
A self-administered questionnaire was distributed to 180 high school students aged 14 to 17 years. Measured variables included socio-economic demographics, smoking status, knowledge of the effects of smoking on general and ocular health, and level of fear as well as level of motivation to quit smoking associated with the following tobacco-related conditions: lung cancer, cardiovascular disease, heart attack, blindness and deafness.
Response rate was 100 per cent. Eleven per cent of responders were smokers. The proportion of smokers who thought smoking could cause blindness was 64.3 per cent while it was 13.5 per cent for non-smokers. The proportion of smokers fearing blindness was 30 per cent, as opposed to 69.8 per cent for non-smokers. The proportion of respondents who thought the presented conditions were 'extremely' or 'very good' reasons to quit were similarly high for all smoking-associated conditions.
These findings suggest teenagers are unaware of the impact smoking can have on ocular health. Smokers did not seem more concerned about vision loss compared to other tobacco-related diseases, as opposed to non-smokers. Our findings suggest vision loss would be a strong motivator to prevent initiation, but not very effective regarding cessation in this group. However, optometrists should be aware teenagers seem receptive to the message that 'smoking can cause blindness' and use this strategy in order to prevent smoking initiation.
尽管大多数人将吸烟与肺癌和心脏病联系在一起，但很少有人意识到吸烟对眼部健康的影响。研究表明，更好地了解这种关联可能会提高戒烟率，尤其是在青少年中。我们研究的目的是确定青少年对吸烟对眼部健康影响的了解程度，以及与几种烟草相关健康状况相关的恐惧程度。
向180名年龄在14至17岁的高中生发放了一份自填式问卷。测量变量包括社会经济人口统计学、吸烟状况、对吸烟对一般健康和眼部健康影响的了解程度、恐惧程度以及与以下烟草相关状况相关的戒烟动机水平：肺癌、心血管疾病、心脏病发作、失明和失聪。
应答率为100%。11%的应答者为吸烟者。认为吸烟会导致失明的吸烟者比例为64.3%，而非吸烟者为13.5%。害怕失明的吸烟者比例为30%，而非吸烟者为69.8%。对于所有与吸烟相关的状况，认为所呈现的状况是“极其”或“非常好”的戒烟理由的受访者比例同样很高。
这些发现表明青少年并未意识到吸烟对眼部健康可能产生的影响。与非吸烟者相比，吸烟者似乎对视力丧失并不比其他烟草相关疾病更担心。我们的研究结果表明，视力丧失将是预防开始吸烟的有力动机，但对于该群体戒烟而言效果并不显著。然而，验光师应该意识到青少年似乎容易接受“吸烟会导致失明”这一信息，并利用这一策略来预防吸烟的开始。
