목적 : MR8 로 제조된 안경렌즈에서 굴절력별로 나누어 투과율을 측정하여 광학적 시험 및 청광 영역을 David L.의 분석법을 적용하여 분석하였다. 방법 : 시중에서 판매되고 있는 MR8 로 제조된 -8.00D, -7.00D, -6.00D, -5.00D, -4.00D, -3.00D, 0.00D의 렌즈를 선정하여 UV-VIS Spectrophotometers(SolidSpec 3700)로 200~1000nm까지 5nm 간격으로 투과율을 측정하고, 청광영역(380~500nm)을 David L.의 청광분석 방법을 적용하여 분석하였다. 결과 : 연구에 선정한 MR8렌즈들 모두 UV영역을 거의 모두 차단하였다. -8.00D의 렌즈가 청광영역에서 투과율 59.56%로 가장 낮게 측정되었고 또한, David L. 분석에 따른 청광영역1과 2에서 낮은 값이 측정되었다. 적외선 영역에서는 모든 렌즈의 투과율이 점진적으로 감소하였다. 그리고 시감투과율에서 평균 23.67%~26.33%의 계산값을 얻었고 -4.00D부터 점진적으로 감소하였다. 결론 : David L.의 분석법을 적용하면, 청광 1영역에서는 최소 41.28%, 최대 46.60%가 측정되었으며, 청광 2영역에서는 최소 87.30%, 최대 97.55%가 측정되었다. 그리고 청광 3영역에서는 최소 86.83%, 최대 96.55%가 측정되었으며 평균 94%였다. 시감투과율에서는 측정된 렌즈 중 -3.00D렌즈가 26.33%으로 가장 높은 값이 계산되었으며, -8.00D렌즈가 23.67%으로 가장 낮은 계산 값을 얻었다.
Purpose : We present a novel method for the analysis of blue light applied by the analysis method of David L. with optical experiment and blue light by measuring the transmittance by dividing it by the refractive power in the spectacle lens made by MR8. Methods : The lenses of -8.00D, -7.00D, -6.00D, -5.00D, -4.00D, -3.00D, and 0.00D manufactured by MR8 being sold in the market, were selected. The transmittance was measured at the intervals of 5 nm from 200 to 1000 nm with UV-VIS Spectrophotometers (SolidSpec 3700), and they were in range of the blue light (380 to 500 nm) analyzed by a David L.'s analysis method. Results : All of the MR8 lenses selected for this study almost completely blocked at the UV range. A lens of -8.00D was measured as the lowest transmittance of 59.56% in the blue light area and low values were measured at the blue areas 1 and 2 according to the analysis of David L.In the infrared ray area, the transmittance of all lenses gradually decreased. The average value of the luminous transmittance was 23.67% ~ 26.33% and then gradually decreased from -4.00D. Conclusion : Applying the analysis of David L., a minimum of 41.28% and a maximum of 46.60% were measured at the blue light 1 area and a minimum of 87.30% and a maximum of 97.55% were measured at the blue light 2 area. A minimum of 86.83% and a maximum of 96.55% were measured at the blue light 3 area, and the average was 94%. The luminous transmittance of the -3.00D lens was 26.33%, which was the highest, and that -8.00D was 23.67%, which was the lowest.
