The Catford Visual Acuity Apparatus is supposed to offer an easy and time-saving possibility for an objective determination of the visual acuity. No useful results were obtained from a survey, including 27 patients of varius age-group, which were examined at the recommended distance. Furthermore, because the examination becomes affected by other negative components, that come into perspective at the optimal distance of examination of 2 meters, this apparatus cannot be recommended for the use of an oculist in his practice.
卡特福德视力仪本应提供一种简便省时的客观测定视力的方法。对包括27名不同年龄组患者在内的一项调查未得到有用结果，这些患者是在推荐距离下接受检查的。此外，由于检查会受到其他负面因素的影响，这些因素在2米的最佳检查距离时会显现出来，因此该仪器不推荐眼科医生在其临床实践中使用。
