Abstract

Purpose: To investigate the effect of tinted spectacle lenses on stereopsis through a change of stereoscopic in accordance with the concentration and color of tinted spectacle lenses Method: I organized adult between the ages of twenty and forty five, and After stereopsis tests wearing a polarizing lens under illumination of 200 Lux at 40 cm distance, stereopsis was measured again for each color and concentration, wearing tinted spectacle lens on the polarizing lens. Results: In a change of stereoscopic in accordance with the concentration, brown stereopsis were significantly increased to $2.04{\pm}32.11^{\prime\prime}$(p<0.05) in 20% concentration, meanwhile, the order in which stereoscopic significantly decreases(p<0.05): green, gray, red. In concentration at 50% and 80%, stereopsis (p<0.05) was significantly reduced (p<0.05) in the order of brown, gray, green, and red, especially, it showed a greater width of decrease in the concentration of 80%. Conclusion: In this investigation, it was found a decrease in stereopsis depending on the concentration and colors of tinted spectacle lenses, therefore, it suggests a necessary to consider the effects of stereopsis when choosing tinted spectacle lenses' concentration and colors.

목 적: 착색안경렌즈의 색상과 농도에 따른 입체시의 변화를 통해 착색안경렌즈가 입체시에 미치는 영향을 알아보고자 한다. 방 법: 20세에서 45세 사이의 성인 남녀 49명을 대상으로, 검사거리 40cm에서 200Lux의 조명하에 편광렌즈를 착용하고 입체시 검사를 한 후, 편광렌즈 위에 착색안경렌즈를 착용하게 하여 각각 색상, 농도별로 입체시를 다시 검사하였다. 결 과: 착색안경렌즈의 농도에 따른 입체시의 변화를 보면 농도 20%에서 갈색의 입체시가 $2.04{\pm}32.11^{\prime\prime}$로 유의(p<0.05)하게 증가하였고, 다음은 녹색, 회색, 적색 순으로 입체시가 유의(p<0.05)하게 감소하였다. 농도 50%와 80%에서 갈색, 회색, 녹색, 적색의 순으로 입체시가 유의(p<0.05)하게 감소했으며, 농도80%일 때의 감소폭이 더 큰 것으로 나타났다(p<0.05). 결 론: 착색안경렌즈의 색상과 농도에 따라 입체시는 감소하는 것으로 나타났으며 착색렌즈의 색상과 농도를 선택할 때 입체시의 영향도 고려되어져야 할 것으로 사료된다.
