초록

목적: 본 연구는 60대 이상의 노년층을 대상으로 착색안경렌즈의 처방이 시력교정의 질에 미치는 영향을 평가하고 가장 효과적인 착색렌즈의 색상을 제시하고자 하였다. 방법: 60대 이상(평균 $71.0{\pm}6.3$세)의 50명(남17, 여33)을 대상으로 원거리 시력이 0.5 이상이 되도록 시험테를 이용하여 교정한 후 무착색, 브라운착색 및 그레이착색렌즈를 덧댐하였다. 각각 착색안경렌즈 덧댐 시의 시력은 원거리 최소가독시력 및 최소분리시력을 측정한 후 LogMAR 시력으로 환산하여 비교하였으며, 시기능은 근거리 입체시와 대비감도를 측정하여 비교하였다. 또한 대상자들의 착색안경렌즈 선호도와 시지각 및 움직임에 대한 자각증상을 설문조사하였다. 결과: 원거리 최소가독시력과 최소분리시력은 무착색렌즈의 사용 시 가장 좋았으며, 브라운착색 및 그레이착색렌즈 순으로 나타났다. 근거리 입체시, 대비감도 및 시지각은 브라운착색렌즈의 사용 시 가장 좋은 것으로 나타났다. 자각적 불편감은 그레이착색렌즈 착용 시 가장 크게 나타났으며, 대상자가 선호하는 안경렌즈는 브라운착색렌즈로 조사되었다. 결론: 이상의 결과로 착색안경렌즈의 사용으로 노년층의 시력과 시기능이 개선될 수 있으나, 시력 및 시기능의 변화가 자각적 만족도와는 반드시 일치하는 것은 아님을 알 수 있었다. 본 연구결과, 1,000 lux정도의 조도에서는 원거리 시생활이 보편화된 노년층에게는 무착색 및 브라운착색렌즈의 사용을, 근거리 작업이 많은 경우에는 브라운 및 그레이착색렌즈의 사용을 제안할 수 있겠다.

Purpose: The study was aimed to suggest the most effective color of the tinted lenses by evaluating the effect of the prescription with tinted lenses on the visual quality of the elderly at the age of the sixty or more. Methods: The visual acuity of fifty subjects at the age of sixty or more (17 males, 33 females with the averaged age of $71.0{\pm}6.3$) were corrected to have the visual acuity at a far distance of 0.5 or more using a trial lens frame, and non-tinted, brown-tinted, and gray-tinted lenses were randomly applied on the trial frame. The minimum legibility and minimum separability were measured at a far distance in the aspect of the visual acuity and calculated as LogMAR and then, the visual acuity was compared. The stereopsis and contrast sensitivity were also estimated at a near distance in the aspect of the visual function. The participants' preference for tinted lenses and their subjective symptoms of the visual perception and the movement were further surveyed. Results: The best minimum legibility and minimum separability was shown when wearing non-tinted lenses, and brown-tinted and gray-tinted lenses were in the next. The stereopsis and the contrast sensitivity at a near distance and the visual perception was the best when wearing brown-tinted lenses. It was surveyed that the subjective discomfort was the biggest when wearing gray-tinted lenses, and brown-tinted lenses were the best in the aspect of the subjective preference. Conclusions: As the result of this study, it was revealed that the visual acuity and visual function could be improved by the use of tinted ophthalmic lenses however, its change of visual acuity and visual function was not completely correlated with the subjective satisfaction. Therefore, the appropriate color of ophthalmic lenses should be selected in accordance with the individual visual perception and the main vision lifestyle in the elderly generation. From the present study, the use of non- or brown-tinted lens and brown- or gray-tinted lens can be recommended for distance work and near work, respectively, in the elderly generation under the illumination of about 1,000 lux.
