영문 초록

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.
