目的：估计的患病率的习惯性视力（VA）水平和视力障碍在芬兰，并评估其与自我报告的视觉functions.Design的相关性：横断面人群为基础的study.Participants：受试者随机选择年龄在30岁或以上的芬兰人口。在7979名符合条件的人中，7393人（93%）接受了访谈，6771人（85%）接受了检查，6663人（84%）接受了远视力评估。方法：参与者接受了家庭访谈和全面检查，包括测量参与者当前眼镜的远视力和近视视力（如果有的话）。使用当前眼镜矫正的远视力和近视视力水平。自我报告的能力，阅读报纸和电视文本和移动的能力，而不受视力下降的限制。结果：患病率良好至中度VA的距离（VA >= 0.5 [>= 20/40]）测量与当前眼镜为95.9%，87.4%的VA水平为0.8（20/25）或更好。习惯性视力损害（VA）的患病率
Purpose: To estimate the prevalence rates of habitual visual acuity (VA) levels and visual impairment in Finland and to assess their correlation with self-reported visual function.Design: Cross-sectional population-based study.Participants: Subjects were selected randomly from the Finnish population aged 30 years or older. Of 7979 eligible people, 7393 (93%) were interviewed, 6771 (85%) were examined, and 6663 (84%) had distance VA assessed.Methods: Participants underwent a home interview and a comprehensive examination including measuring binocular VA for distance and for near with the participants' current spectacles, if any.Main Outcome Measures: The level of VA for distance and for near with current spectacle correction. The self-reported capability to read newsprint and television text and the ability to move about without being restricted by reduced vision.Results: The prevalence of good to moderate VA for distance (VA >= 0.5 [>= 20/40]) measured with current spectacles was 95.9%, and 87.4% had a VA level of 0.8 (20/25) or better. The prevalence of habitual visual impairment (VA
