When colours go beyond your vision

Colour allows us to recognise objects and it facilitates our visual memory. Scientific evidence suggests that colour also has a deeper effect that goes beyond vision, as it is connected to how we feel. In the eyewear market, tinted sunglasses lenses are normally used to filter the harmful effects of sun light, enhance contrast and offer better vision.
