Abstract: The present invention provides a material for intraocular lens which has improved hydrolysis resistance. The material for intraocular lens according to the present invention is obtained by polymerizing a monomer composition comprising: a base monomer, a hydrophilic monomer, and a cross-likable monomer, wherein the base monomer comprises an aromatic ring-containing acrylate monomer and an alkoxyalkyl methacrylate monomer having an alkoxyalkyl group having four or less carbon atoms. A blending ratio on a molar basis of the methacrylate monomer with respect to the acrylate monomer in all the monomer components contained in the monomer composition is 0.25 to 1.00.

Abstract: A flying object 20 is provided with a rotor blade 200 that generates lift and thrust by rotating and a rotating electrical machine unit that rotates the rotor blade 200. The rotor blade 200 receive wind power and rotate when not flying. The rotating electrical machine unit generates electric power based on a power that rotates the rotor blades 200 when not flying. In addition, the flying object 20 may be provided with a power storage device 230 that stores electric power generated by the rotating electrical machine unit. In addition, the flying object 20 may be provided with a detachably connected cartridge 260 that has a desired function.
