Novel azo-based reactive yellow dyes and a process for manufacturing and using ocular devices having blue light absorption properties. Intraocular lenses so produced block blue light from reaching the retina of an eye implanted with the IOL. By blocking blue light from reaching the retina, the IOL thereby prevents potential damage to the retina.

L'invention concerne de nouveaux colorants jaunes réactifs à base azoïque, un procédé de production et l'utilisation de dispositifs oculaires ayant des propriétés d'absorption de lumière bleue. Des lentilles intra-oculaires ainsi produites empêchent la lumière bleue d'atteindre la rétine d'un oeil doté d'un implant intra-oculaire. En empêchant la lumière bleue d'atteindre la rétine, la lentille intra-oculaire empêche les éventuels dommages causés à la rétine.
