Em condições normais, as moléculas fotocrómicas têm uma forma dobrada que as torna transparentes. Ao absorver a luz ultravioleta, a sua forma muda, a estrutura molecular abre-se e absorve a luz visível. As duas formas da molécula fotocrómica − aberta e fechada − existem em equilíbrio com uma ligação que é continuamente quebrada e reconstruída.
A molécula fotocrómica muda constantemente entre o estado transparente e escuro. Se a lente for exposta a níveis significativos de luz UV, a maioria das moléculas estará no estado aberto, escurecendo as lentes. Na ausência de luz UV, as moléculas permanecerão fechadas, resultando em lentes claras.
NEOCHROMES, AS LENTES DE TECNOLOGIA DE PONTA PARECEM NATURAIS E TORNAM SE UM HÁBITO PARA O UTILIZADOR.
Antes da exposição à luz UV, a lente está no seu estado mais transparente.
Quando a lente é exposta à luz UV pela primeira vez, as moléculas fotocrómicas começam a mudar de claras para escuras.
As lentes estão no auge da sua ativação. A transmissão de luz, a cor ativada e a uniformidade da cor podem ser avaliadas neste estado.
O clareamento rápido é essencial. Começa quando a luz UV já não incide sobre a lente. Quanto mais curto o clareamento, mais confortável e funcional é a lente para o utilizador.

DE NEOCHROMES
A TEMPERATURA E O SEU EFEITO SOBRE A TECNOLOGIA FOTOCRÓMICA
Qualquer lente fotocrómica é afetada pela temperatura. Com temperaturas frias, as lentes fotocrómicas escurecem mais e demoram mais tempo a clarear. Com temperaturas mais quentes, as lentes não escurecem tanto e voltam a clarear mais rapidamente. Esta é uma característica do estado de equilíbrio num sistema fotocrómico.
Nas lentes Neochromes, é dada atenção especial ao desempenho a altas temperaturas. Com uma temperatura de 33 °C, alcançarão uma escuridão funcional semelhante a muitas lentes polarizadas. A esta temperatura, o tempo de clareamento é de cerca de 32 segundos.
