摘要： The present invention provides methods for controlling the optical properties of a light transmissive article. The method includes identifying a target window in an Abbe diagram comprising reference polymeric materials. The method further includes selecting a first polymeric material from the reference polymeric materials and compounding the first polymeric material with a stable UV chromophore to provide a first polymer composition. The method further includes transforming the first polymer composition to provide the light transmissive article, wherein the light transmissive article has an Abbe number and a refractive index which falls within the target window. Light transmissive articles prepared using the above methods are also provided.
