BLUE EDGE FILTER OPTICAL LENS
Optical lenses are described and include a polymeric interference filter disposed on a curved polymeric substrate. The optical lens has an average light transmission of less than 2% across a band of blue light from 400 nm to at least 420 and up to 440 nm and substantially transmits blue light greate...

| Zusammenfassung: | Optical lenses are described and include a polymeric interference filter disposed on a curved polymeric substrate. The optical lens has an average light transmission of less than 2% across a band of blue light from 400 nm to at least 420 and up to 440 nm and substantially transmits blue light greater than 450 nm.
L'invention concerne des lentilles optiques comprenant un filtre interférentiel polymère disposé sur un substrat polymère incurvé. La lentille selon l'invention présente une transmission de lumière moyenne de moins de 2% sur une bande de lumière bleue allant de 400 nm à au moins 420 et jusqu'à 440 nm, et transmet sensiblement une lumière bleue supérieure à 450 nm. |
