초록

자외선 완전차단 및 청색광을 일부 차단하고 광변색성을 가지는 편광안경렌즈를 개발하였다. 심야 운전이나 반사광에 의한 눈부심을 획기적으로 줄이고 자외선이 강한 공간에서는 선글라스 역할을 하며 평상시는 안경렌즈로 사용할 수 있는 기능성 안경렌즈이다. 광변색성은 명반응에서는 0.5초 암반응에서는 3초 정도의 회복시간이 걸렸다. 편광기능은 95% 정도를 얻었다. 자외선은 완전히 차단되었고 청색광은 30%정도의 저감 효과를 얻었다. 광변색성 및 자외선차단기능과 편광기능을 하나로 결합한 렌즈는 국내 시장을 조사한 결과 최초의 시도이다.

A polarizing spectacle lens having a perfect blocking of ultraviolet light and a partial blocking of blue light and having photochromic properties has been developed. It is a functional spectacle lens which can be used as a spectacle lens in the daytime, which plays a role of sunglass in a space with strong ultraviolet rays, dramatically reducing glare caused by late-night driving or reflected light. Photochromism was recovered in 0.5 second dark reaction and 3 seconds recovery time. The polarization function was about 95%. Ultraviolet rays were completely blocked and blue light was reduced by about 30%. A lens that combines photochromic and UV blocking and polarization functions is the first attempt at investigating the domestic market.
