The blue light edition of Warby Parker is a smart choice of the time and worth it from different points of view. The blue light glass helps prevent harmful blue light from the sun, and screens. It is also supposed to provide you an opportunity to sleep soundly by blocking the blue light effect at night.   This glass is really helpful while using mobile and computer. It can also reduce eye irritation and other problems. Warby Parker can attach a blue light glass for just 50$ and all those benefits make it worth it.
