Duco Glasses offers a wide range of glasses for men and women. We also offer blue light blocking glasses and Nova is one of them. The human eye hasn't evolved to stare at a screen many hours a day, and blue light from computer screens can potentially lead to health issues down the road, such as retina macular degeneration as well as cataracts. This glasses can block the bluelight from your laptop, computers, monitor, television, ipad, and any other screens.
