To characterize and discover the determinants of the frequency of wear (FOW) of contact lenses.
Survey forms were sent to contact lens fitters in up to 40 countries between January and March every year for 5 consecutive years (2007-2011). Practitioners were asked to record data relating to the first 10 contact lens fits or refits performed after receiving the survey form. Only data for daily wear lens fits were analyzed.
Data were collected in relation to 74,510 and 9,014 soft and rigid lens fits, respectively. Overall, FOW was 5.9±1.7 days per week (DPW). When considering the proportion of lenses worn between one to seven DPW, the distribution for rigid lenses is skewed toward full-time wear (7 DPW), whereas the distribution for soft daily disposable lenses is perhaps bimodal, with large and small peaks at seven and two DPW, respectively. There is a significant variation in FOW among nations (P<0.0001), ranging from 6.8±1.0 DPW in Greece to 5.1±2.5 DPW in Kuwait. For soft lenses, FOW increases with decreasing age. Females (6.0±1.6 DPW) wear lenses more frequently than males (5.8±1.7 DPW) (P=0.0002). FOW is greater among those wearing presbyopic corrections (6.1±1.4 DPW) compared with spherical (5.9±1.7 DPW) and toric (5.9±1.6 DPW) designs (P<0.0001). FOW with hydrogel peroxide systems (6.4±1.1 DPW) was greater than that with multipurpose systems (6.2±1.3 DPW) (P<0.0001).
Numerous demographic and contact lens-related factors impact FOW. There may be a future trend toward a lower FOW associated with the increasing popularity of daily disposable lenses.
描述并发现接触镜佩戴频率（FOW）的决定因素。
在每年的 1 月至 3 月，向多达 40 个国家/地区的隐形眼镜配镜师发送调查表格，连续 5 年（2007-2011 年）进行调查。从业者被要求记录在收到调查表格后进行的前 10 次隐形眼镜适配或重新适配的数据。仅对日戴镜片的适配数据进行分析。
共收集到软镜和硬镜的适配数据分别为 74510 次和 9014 次。总体而言，FOW 为每周 5.9±1.7 天（DPW）。考虑到镜片佩戴 1 至 7 DPW 的比例，硬镜的分布偏向于全天佩戴（7 DPW），而软日戴一次性镜片的分布可能呈双峰状，分别在 7 DPW 和 2 DPW 处有较大和较小的峰值。各国之间的 FOW 存在显著差异（P<0.0001），从希腊的 6.8±1.0 DPW 到科威特的 5.1±2.5 DPW。对于软镜，FOW 随年龄的降低而增加。女性（6.0±1.6 DPW）比男性（5.8±1.7 DPW）更频繁地佩戴镜片（P=0.0002）。与球性（5.9±1.7 DPW）和散光（5.9±1.6 DPW）设计相比，佩戴老视矫正镜片（6.1±1.4 DPW）的 FOW 更高（P<0.0001）。与多功能系统（6.2±1.3 DPW）相比，使用双氧水系统（6.4±1.1 DPW）的 FOW 更高（P<0.0001）。
许多人口统计学和接触镜相关因素都会影响 FOW。随着日戴一次性镜片越来越受欢迎，FOW 可能会出现降低的趋势。
