Title (EN) WATER-SOLUBLE UV-ABSORBING COMPOUNDS AND USES THEREOF
(FR) COMPOSÉS HYDROSOLUBLES ABSORBANT LES UV ET LEURS UTILISATIONS
Abstract:
(EN) Described herein are dimethyl acetal-containing UV-absorbing compounds and their uses in preparing UV-absorbing polyvinyl alcohol prepolymers suitable for producing UV- absorbing contact lenses capable of blocking ultra-violet ("UV") radiation and optionally (but preferably) violet radiation with wavelengths from 380 nm to 440 nm, thereby protecting eyes to some extent from damages caused by UV radiation and potentially from violet radiation. This invention also provides a UV-absorbing polyvinyl alcohol prepolymer.
(FR) L'invention concerne des composés absorbant les UV contenant un diméthylacétal et leurs utilisations dans la préparation de prépolymères d'alcool polyvinylique absorbant les UV se prêtant à la production de lentilles de contact absorbant les UV capables de bloquer le rayonnement ultraviolet ("UV") et éventuellement (mais de préférence) le rayonnement violet ayant des longueurs d'ondes comprises entre 380 et 440 nm, pour protéger ainsi les yeux dans une certaine mesure contre les dommages provoqués par un rayonnement UV et potentiellement par un rayonnement violet. Un prépolymère d'alcool polyvinylique absorbant les UV est en outre décrit.
