Abstract

This study researched how the refraction error and illumination influence to contrast sensitivity when we wear the circle contact lenses. The study population comprised 16 students and adults(5 of Male, 11 of Female). The study population comprised 16 students and adults(5 of Male, 11 of Female), We measured the contrast sensitivity on uncorrected vision, according to color of circle contact and change the illumination of laboratory. The contrast sensitivity by illumination decreased than unaided vision when they wore the color contact lenses and more increased mesopic than photopic. Compared between black and brown lenses, brown was higher the contrast sensitivity than black. Also emmetropia had significantly differences when we compared the contrast sensitivity of subjects who had emmetropia, myopia and myopia astigmatism whether refractive error has or not. Therefore, it is important to provide sufficient understanding and recognition of color contact lenses.

본 연구는 굴절이상도와 조도가 써클콘택트렌즈 착용 시 대비감도에 어떠한 영향을 미치는 지 조사하였다. 연구대상자는 총 16명(남5명, 여 11명)을 대상으로 하였다. 대비감도는 나안상태, 써클 콘택트렌즈의 색상별, 검사실의 조도에 따라 측정하였다. 조도에 따른 대비감도는 컬러콘택트렌즈를 착용했을 때 나안상태보다 감소하였고, 암소시보다 명소시일 때 대비감도가 증가하였다. 브라운과 블랙 두 가지 컬러 콘택트렌즈의 대비감도를 비교하였을 때 블랙보다는 브라운 컬러의 콘택트렌즈에서 대비감도가 높았다. 또한 굴절이상유무에 따른 정시안, 근시안, 근시성난시안 대상자의 대비감도 비교에서 정시안대상자에서 조도에 따른 대비감도가 유의한 차이를 보였다. 이는 컬러콘택트렌즈 착용자들의 충분한 이해와 인식이 필요할 것이라고 사료된다.
