Abstract
To investigate the influence of the variation of conic coefficient of the front surface on the RMS SD(Root Mean Square Spot Diameter) in a back focal plane, we use programs which are Cove V and LOSA 2.0. We consider a spectacle lens with back vertex power of -4.00D, diameter of 70 mm, the front surface powers which are 2.00D, 4.00D, 6.00D, and 8.00D, and the indices which are
본 연구에서는 안경렌즈 전면의 conic 계수 변화에 따른 상측정점초점면에서의 착락원 직경 변화를 조사하기 위해 Code V와 LOSA 2.9 프로그램을 사용하였다. 이때 상측정점굴절력은 -4.00D이고 직경은 70mm인 근시교정용 안경렌즈를 고려하였으며, 전면 굴절력은 2.00D, 4.00D, 6.00D, 그리고 8.00D인 경우를, 굴절률은
