본 연구는 국내에 유통되고 있는 안경렌즈의 굴절력을 조사하여 안경렌즈 굴절력의 신뢰성을 평가하였다. 실험에 사용한 렌즈는 굴절률별로 중굴절(1.55~1.56), 고굴절(1.60~1.61), 초고굴절(1.67) 렌즈 총 8개 회사 398개를 사용하였으며, 식품의약품안정청의 의료기기에 대한 기준규격을 사용하여 렌즈 굴절력의 오차와 적합률을 실험하였다. 많은 렌즈에서 굴절력 허용오차를 벗어났으며 전체 안경렌즈에서 81.61%의 적합률을 나타내었다.
This study is to investigate the refractive power of spectacle lenses, which are being sold in Korea and evaluate reliability of refractive power. We used samples of three hundred and ninety eight spectacle lenses of eight company in total. Refractive indices of each samples which were used in experiment were medium index (1.55~1.56), high index(1.60~1.61) and extra high index(1.67). We tested the errors and conformity of refractive power of spectacle lenses by using the medical instrument standard of KFDA. We found that they deviated from the permitting value in many spectacle lenses and the conformity of refractive power was 81.61% in total spectacle lenses.
