摘要 |
FIELD : medicine.SUBSTANCE : ophthalmic lens contains a transparent substrate with a front main surface and a rear main surface. At least one of the main surfaces is coated with a multi-layer anti-reflective coating containing a set of at least one layer with a high refractive index (HI), having a refractive index greater than or equal to 1.55, and at least one layer with a low refractive index (LI) having a refractive index of less than 1.55. Multilayer antireflection coating has : - the average coefficient of light reflection in the visible region for photopic vision Rv, which is less than or equal to 2.5?%, preferably less than or equal to 0.9?%, at least for a dip angle less than 35? - the average coefficient of reflection of light in the visible region for scotopic vision, Rv' , which is less than or equal to 0.5?%, preferably less than or equal to 0.4?%, at least for an angle of incidence less than 35?EFFECT : technical result is the creation of an antireflection coating capable of reducing the reflection coefficient in the visible region in the case of both photopic vision and scotopic vision.16 cl, 2 dwg, 2 tbl |
