Wearing glowing contacts during sleep may prevent blindness
Caltech researchers have developed a glow-in-the-dark contact lens that could help prevent blindness in diabetes patients. The condition, diabetic retinopathy, begins with an insufficient supply of oxygen to the retina, researchers noted. Hence, the lenses are designed to reduce the retina's night-time oxygen demand by providing rod cells the faintest amount of light while the wearer sleeps.
