Abstract
Analysis of accommodation amplitude has been conducted for 137 adults, living in rural area, aged from their fifties to eighties. The methods included measurement of correction power for distance via auto-refractometer, measurement of near power based on trial frame and trial lens set, and calculation of effective accommodation amplitude using 1/2 and 2/3 of the maximum accommodation amplitude. The research results for participants aged in their fifties, sixties, seventies, and eighties showed 1.84~2.46D, 1.55~2.06D, 1.43~1.90D, and 1.22~1.62D respectively. It is relatively higher than the existing knowledge regarding accommodation amplitude associated with age.
농촌지역 50대~80대 남녀 137명을 대상으로 자동 안굴절력계에 의한 원용 교정도수 측정, Trial frame와 Trial lens set을 사용한 근용 도수 측정, 최대조절력의 1/2과 2/3를 사용하였을 때의 유효조절력 산정 등을 통하여 조절력을 분석해 보았다. 그 결과 50대에서는 1.84~2.46D, 60대에서는 1.55~2.06D, 70대에서는 1.43~1.90D, 80대에서는 1.22~1.62D로 조사되어 기존에 알려진 나이에 따른 조절력에 비해 다소 높게 나타났다.
