Contact lenses made with millions of gold nanoparticles, no bigger than a speck of dust, could combat a common type of colour blindness. These ‘gold dust’ particles filter out certain wavelengths of light, so the brain can distinguish between different colours, particularly reds and greens, more easily. Around one in 12 men and one in … Read more
