Abstract

Purpose: To evaluate stability and effects of photochromic lenses in light-sensitive patients. Methods: Analyzing 65 patients, this research employed a standardized survey, fundus examination, and slit-lamp biomicroscopy to evaluate the changes in photophobia, tears, asthenopia, and the deterioration of outdoor visual acuity after wearing photochromic lenses for one month. Measurement of visual acuity was performed outdoors at noon on a bright day using Dr. Hahn’s standard test chart for 3 m. Results: Photochromic lenses, considerably decreased photophobia, tears, and asthenopia. The ‘normal’ visual acuity of 38 patients was established without photochromic lenses. Re-examination after the lenses had been worn for a specified period of time showed that 29 subjects could discern at least one line higher than their ‘normal’ acuity. Conclusions: Photochromic lenses reduced photophobia and the disabling effect of bright light such that comfort was increased. Not only did the lenses improve vision, they also enhanced the overall quality of vision.

목적 : 눈부심 환자에서 광변색 안경렌즈의 효과와 안정성을 평가하고자 한다. 대상과 방법 : 여러 가지 원인의 눈부심 환자 65명을 대상으로 광변색 안경렌즈를 착용 전과 착용 1개월 후에 눈부심, 눈물, 눈피로, 실외에서 시력저하의 호전 여부 및 안정성에 대하여 표준화된 설문지와 세극등현미경검사, 안저검사를 통해 비교, 평가하였다. 시력 측정은 맑은 날 정오 12시 실외에서 한식표준시시력표 3M를 이용하여 시행하였다. 결과 : 광변색 안경렌즈를 착용하였을 때 눈부심, 눈물, 눈피로 현상이 유의하게 감소하였다. 실외에서 시력검사 결과 38명 중 29명에서 안경 착용 후에 1줄 이상의 시력 호전을 보였다. 결론 : 광변색 렌즈를 착용하였을 때 눈부심을 줄이고 눈부심에 따른 시력장애를 저하시켜 환자의 편안함을 증진시키는 효과가 나타났다. 단순히 시력을 증진시키는 효과 뿐만 아니라 시력의 질 향상에도 효과가 있는 것으로 나타났다.
