One hundred thirty-one new hydrophilic lenses made by 3 manufacturers were randomly selected from an optometry clinic for measurement and inspection. Approximately 60% of the base-curve specifications fell within the following ranges for the measured dimensions: Bausch & Lomb Soflens contact lenses, less than 0.150 mm; Milton Roy Naturvue lenses, less than 0.375 mm; Soft Lens Inc. Hydrocurve, less than 0.225 mm. More than 65% of the lenses supplied by all the manufactures were within 0.25 D of the power specification. About two-thirds or more of all lenses had a central thickness and overall diameter within 0.04 mm and 0.40 mm, respectively, of the manufacturers' specifications, although there were notable differences among manufacturers. Most of these new lenses exhibited surface scratches and other surface defects, and many lenses had edge defects.
从一家验光诊所随机选取了由3家制造商生产的131副新型亲水镜片进行测量和检查。对于测量尺寸，约60%的基弧规格落在以下范围内：博士伦Soflens隐形眼镜，小于0.150毫米；米尔顿·罗伊Naturvue镜片，小于0.375毫米；Soft Lens Inc. Hydrocurve镜片，小于0.225毫米。所有制造商提供的镜片中，超过65%的镜片屈光度规格在±0.25 D范围内。尽管各制造商之间存在显著差异，但所有镜片中约三分之二或更多镜片的中心厚度和总直径分别在制造商规格的±0.04毫米和±0.40毫米范围内。这些新镜片大多有表面划痕和其他表面缺陷，许多镜片还有边缘缺陷。
