  • CONTACT LENS COMPRISING CERIA PARTICLES AND METHOD OF FABRICATING THE SAME
    Publication number: 20190129069
    Abstract: The present disclosure relates to a contact lens containing ceria particles. Further, the present disclosure relates to a method for manufacturing a contact lens containing ceria particles. The method includes preparing ceria particles; preparing poly-2-hydroxyethyl methacrylate (PHEMA or poly-HEMA) in a form of cross-linked hydrogel; mixing the ceria particles and the monomer mixture for poly-2-hydroxyethyl methacrylate (PHEMA or poly-HEMA) with each other to form a mixture; and injecting the mixture in a mold having a contact lens shape; and performing photo-curing polymerization of the mixture. The contact lens effectively eliminates the reactive oxygen species and harmful radicals that are identified as a cause of eye diseases.
