WebFluorosilicone acrylate lenses are likely to have a refractive index between 1.420 and 1.460, whereas an index of 1.460 or greater usually indicates a silicone acrylate material. The refractive index of PMMA is 1.49. Unlike in spectacle lens dispensing, refractive index has rarely been a factor in the choice of rigid lens material. WebOct 4, 2024 · In general, acrylic adhesives bond better at medium temperatures, ie in a temperature range between 0°C and 100°C. On the other hand, silicone adhesives have better adhesion at lower temperatures, ie below 0°C, as well as at higher temperatures, ie above 100°C. So it seems that silicone adhesives are rather standard and preferred for …
