摘要

The present invention is intended to provide a high UV screening agent filled contact lenses effective The A UV absorption instrument, such as contact lenses, are produced by including UV absorbing compounds in the instrument. UV absorbing compounds, water is insoluble, and / or average diameter can be present in the UV-absorbing nanoparticles of less than 10nm. UV absorbing nanoparticles incorporated into the instrument by polymerizing a monomer mixture containing a UV-absorbing nanoparticles, to form a device comprising a UV-absorbing nanoparticles. UV absorbing compounds or UV absorbing nanoparticles by placing the instrument in the dispersion of UV-absorbing nanoparticles in a non-aqueous solvent swell solution or instrument UV absorbing compounds, are incorporated. UV absorbing compounds or UV absorbing nanoparticles, it is injected into the swollen device is held in the instrument upon removal of non-aqueous solvents [Selection Figure Figure 1
