| description | The invention relates to the technical field of spectacle materials, and particularly discloses a contact lens material, a preparation method thereof, and contact lenses. The preparation method of thecontact lens material comprises the following steps: mixing an acidic collagen solution with a hydrophilic acrylic monomer to obtain a mixed solution 1; mixing the hydrophilic acrylic monomer with ahydrophobic acrylic monomer to obtain a mixed solution 2; mixing the mixed solution 1 and the mixed solution 2, and carrying out a polymerization reaction to obtain the contact lens material, whereinthe hydrophilic acrylic monomer is obtained by carrying out a polymerization reaction on 3-isopropenyl-alpha,alpha-dimethylbenzyl isocyanate and D-glucose polyethylene oxide. Compared with like materials in the prior art, the contact lens material provided by the invention has higher light transmittance. Meanwhile, the contact lens material also has good biocompatibility, tensile strength and refractive index.
