The invention relates to hydrogels containing water and polyethylene glycol-dimethacrylates in a polymerized form. The polymethacrylate blocks are so short that they form no proper phase. The invention further relates to methods for producing said hydrogels. The inventive hydrogels are provided with reduced haze and are used as materials for contact lenses, electrophoresis gels, membrane materials, and sound-absorbing materials.
