The patent application (Publication Number: US20240026145A1) describes an innovative ocular lens made from a polymer material obtained by polymerizing a specific composition. The composition includes a siloxane monomer with a siloxane bond and a siloxane-free crosslinkable monomer devoid of any siloxane bond. The crosslinkable monomer contains an alkylene glycol chain with 6 or more repeating units and polymerizable groups at both ends. The chain moiety of the crosslinkable monomer can have 6 to 50 alkylene glycol repeating units, including ethylene glycol, propylene glycol, or butylene glycol units.

Furthermore, the polymerizable composition may also contain a hydrophilic polymer, with specific blending ratios of the crosslinkable monomer and other components. The patent application outlines various parameters such as the HLB value of the crosslinkable monomer, the weight average molecular weight of the siloxane monomer, and the stress relaxation rate and Young's modulus of the resulting polymer material. Additionally, the ocular lens described in the patent is specifically designed as a contact lens. The detailed specifications provided in the patent application aim to enhance the performance and comfort of ocular lenses, potentially offering improved vision correction and wearing experience for users.
