Abstract
Composite hydrogel films for contact lenses and the methods of manufacturing are provided. The composite hydrogel films are formed by the following steps of: mixing a hydrogel precursor with nanospheres dispersed in a colloid; evaporating the solvent in the mixture; curing the hydrogel to form a composite hydrogel film having nanospheres arranged in amorphous arrays. The composite hydrogel films selectively reflect light in hazardous wavelengths.
