Abstract

Purpose : This study was to investigate the change of accommodative functions by different color density and color of colored lenses. Methods : Participant had a normal NPC and no dyschromatopsia, phoria and eye disease, also had no histories of eye surgery in 31 students of university. Their accommodative functions were measured according to 50%, 80% density of the gray, blue, brown lens and non-colored lenses. Tests of accommodative functions performed include amplitude of accommodation, accommodative facility, relative accommodation, and accommodative lag. Results : The amplitude of accommodation and accommodation lag were increased when wearing the colored lens. Negative relative accommodation was more increased when wearing the colored lens than achromatic. Positive relative accommodation increased when wearing the blue color lens density by 50%. Also, accommodation facility increased when wearing the colored lens, but, as the density of the color increased, the accommodation facility was decreased. Conclusion : As since the accommodation function changes according to density of the colored lenses, working distance and environment of the wearing colored lens should be considered when selecting density and color of colored lenses.

목적 : 본 연구에서는 착색렌즈 농도와 색상에 따라 눈의 조절기능에 변화가 있는지 알아보고자 하였다. 방법 : 연구대상자는 폭주값이 정상, 안위이상과 색각이상, 안질환이 없으며, 안과관련 수술 경험이 없는 20대 남녀 대학생 31명을 대상으로 무착색렌즈와 50%, 80%로 농도로 착색된 gray, blue, brown렌즈를 착용하고 조절기능을 측정하였다. 조절기능검사는 조절력, 조절효율, 양성 음성 상대조절검사 및 조절래그검사를 시행하였다. 결과 : 본 연구 대상자들은 착색렌즈를 착용 하였을 때 조절력과 조절래그가증가하였으며, 음성상대조절력은 무착색렌즈 착용 시 보다 착색렌즈 착용하였을 때 양안, 단안, 좌안에서 증가하였다. 양성상대조절력은 blue 50%착용 시 크게 나타났다. 또한, 착색렌즈를 착용 하였을 때 조절용이성은 증가하였으나, 착색렌즈의 농도가 증가함에 따라 조절용이성은 감소하였다. 결론 : 착색렌즈의 농도에 따라 조절기능의 변화가 나타나므로 착색렌즈 농도 및 색상 선택 시 작업거리, 착색렌즈 착용 환경 등을 고려하여 선택해야 할 것으로 사료된다.
