Other than sunlight, we live in a world of artificial light source from fluorescent light, digital devices like smartphones, LED appliances, and these emit blue light, which is made up of two types – good and bad. While the the good blue turquoise light is essential to regulate our sleep / wake cycle, memory and cognitive performance, the bad blue violet contributes to cataract, and also damages retina cells causing AMD (Age Related Macular Disease), while increasing risks to other eye diseases.
