Glases were seen as interviewing the participants and contact lenses were hard to be idetified unless condestants say the truth about wearing it or not.

本数据集通过随机问询方式采集，用于记录受访者是否佩戴各类矫正镜片（corrective lenses），包括框架眼镜（glasses）与隐形眼镜（contact lenses）。研究人员随机选取25名在校园道路行走的受试者，询问其年龄与佩戴的矫正镜片类型。本实验涉及的变量如下：
- 性别（Gender）：通过外观直接记录，未主动问询受试者性别。
- 年龄（Age）：直接询问每位受试者的年龄，未要求其提供身份证明以核实年龄，仅以受试者自述年龄为准，其真实性无法确认。
- 矫正镜片佩戴情况（Variables/DATA）：问询受试者是否佩戴矫正镜片，类型为框架眼镜或隐形眼镜。其中框架眼镜可通过访谈直接观察确认，但隐形眼镜除非受试者主动告知，否则难以识别。
