More Information
Summary:Described herein is a cost-effective and time-efficient method for producing UV- and HEVL-absorbing silicone hydrogel contact lenses capable of blocking ultra-violet ("UV") radiation and high-energy-violet light (HEVL) with wavelengths from 380 nm to 440 nm, thereby protecting eyes to some extent from damages caused by UV and HEVL radiation. This invention also provides UV- and HEVL-absorbing absorbing contact lenses made according to a method of the invention. L'invention concerne un procédé rentable et efficace en temps permettant de produire des lentilles de contact en hydrogel de silicone absorbant les UV et HEVL aptes à bloquer un rayonnement ultraviolet ("UV") et une lumière violette de haute énergie (HEVL) présentant des longueurs d'onde de 380 nm à 440 nm, protégeant ainsi les yeux dans une certaine mesure contre des dommages causés par un rayonnement UV et HEVL. Cette invention concerne également des lentilles de contact absorbant les UV et HEVL fabriquées selon un procédé de l'invention.
