Abstract
To study the ametropia and the sort of glasses, especially progressive multifocal lens, for near purpose on Middle aged & Manhood. 500 adults were tested by the object and subject methods. Among the 500 adults, myopia is 22.4%, hyperopia is 61.4%, and emmetropia is 16.2%, respectively. In test of astigmatism, the amount of astigmatism for the age of forty one to under forty five with-the rule is 28%, the amount of astigmatism against-the rule is 43% and the amount of astigmatism with oblique is 11%, respectively. Whereas, the amount of astigmatism for the age of fifty six to under sixty with-the rule is 10%, the amount of astigmatism against-the rule is 71% and the amount of astigmatism with oblique is 19%, respectively. With-the-rule decreased with increasing age while against-the-rule increased with increasing age. The oblique astigmatism relationship to age could not be determined. The ratio of the progressive multifocal lens was 67.3% for male and 35% for female.
본 연구는 서울의 중 장년 성인남녀를 대상으로 타각적, 자각적 굴절검사를 시행하여 비정시의 정도 및 굴절이상을 분석하였고, 노안안경 착용자의 노안안경 분포 및 누진다초점렌즈 착용에 관해 연구 조사하였다. 총 근시는 22.4%, 원시는 61.4% 그리고 정시는 16.2%로 나타났다. 연령에 따른 난시의 분포는 41세~45세는 직난시 28%, 도난시 49%, 그리고 사난시 23%로 나타났으며, 56세~60세는 직난시 10%, 도난시 71%, 그리고 사난시 19%로 나타났다. 이는 연령이 증가함에 따라 직난시는 감소하고, 도난시는 증가하는 경향을 확인할 수 있었다. 사난시는 연령 변화에 크게 영향을 받지 않는다. 누진다초점렌즈착용의 남녀비율은 남성 67.3%와 여성 35%로 남성이 여성보다 보다 많았다.
