Patient preference for the Varilux2 lens, a progressive addition multifocal lens, was compared to that of a standard straight-top 25 multifocal. Forty-eight first-time multifocal candidates were fitted with both lens designs, which were then each worn for two three-week periods in succession. The subjects were then asked to state their preference by choosing the lens design they would prefer to continue to wear. Twenty-five of the 48 subjects (52%) preferred the Varilux2 lens design (as compared to the ST-25). The results indicate that the Varilux2 progressive addition lens design is an acceptable method of correction for first time multifocal candidates. The study analyzes patient factors (sex, refractive error, addition power, etc.) in relation to final lens design selection.
将一款渐进多焦点镜片Varilux2的患者偏好与一款标准直顶25多焦点镜片进行了比较。48名初次佩戴多焦点镜片的受试者被配戴上这两种镜片设计，然后每种镜片连续佩戴两个三周的时间段。之后，要求受试者通过选择他们更愿意继续佩戴的镜片设计来表明自己的偏好。48名受试者中有25名（52%）更喜欢Varilux2镜片设计（与ST - 25相比）。结果表明，Varilux2渐进多焦点镜片设计是初次佩戴多焦点镜片的受试者可接受的矫正方法。该研究分析了与最终镜片设计选择相关的患者因素（性别、屈光不正、附加度数等）。
