Abstract

Purpose: This study was to investigate color distortion by colors and luminous transmittance of lenses with word-color test included in computerized neurocognitive function test (CNT). Methods: 32 subjects aged $21.97{\pm}1.58$ years with no ocular disease and color vision deficiency were selected. Four colors of tinted lenses, which were red, green and blue included in the primary colors of light and pink, and word-color test in CNT to evaluate changes in cognitive function by color distortion were used. Results: Response time was not significantly increased in green, blue, and pink among four colors, but significantly increased in only red color. And response time was significantly increased below 46% of luminous transmittance in red color. Conclusions: It should be cautious and careful of the red-tinted lens choice because red color with below 46% of luminous transmittance can distort colors of objects, and it could be related to safety problem. It is suggested that word-color test could be extensively used for further studies on color recognition.

목적: 전산화 신경인지기능 검사(CNT)에 속해있는 단어-색채검사를 이용하여 렌즈의 색상과 시감투과율에 의해 나타나는 색상왜곡을 알아본다. 방법: 안질환과 색각이상이 없는 평균나이 $21.97{\pm}1.58$세의 32명을 대상자로 선정하였다. 빛의 삼원색에 해당하는 red, green, blue에 pink를 추가하여 총 4가지 색상의 렌즈를 사용하였으며, 색상왜곡으로 인한 인지변화를 측정하기 위해 CNT 중 단어-색채검사를 사용하였다. 결과: 4가지 렌즈색상 중 green, blue, pink에서는 반응시간이 통계적으로 유의하게 증가하지 않았으나, red에서는 통계적으로 유의하게 반응시간이 증가하였다. Red 중 시감투과율 46% 이하에서 반응시간이 통계적으로 유의하게 증가하기 시작하였다. 결론: 46% 이하의 시감투과율을 가지는 red 렌즈는 사물을 보는데 색상왜곡의 원인으로 작용하여 안전문제를 일으킬 수 있으므로 렌즈색상으로 선택 시 주의를 기울여야 한다. 단어-색채검사가 색상인지와 관련되는 추후 연구에 폭넓게 활용될 수 있다는 것을 제안한다.
