Our glasses come with blue light blocking lenses by default, but we understand the general need for glasses is to correct vision and blue light blocking is not necessary for everyone, especially those who stare at electronic screens for no more than 4 hours a day.
So if you don't want to block blue light in your glasses, add "NO BLUE LIGHT" or "NO BL" in the Remarks of Checkout page, then we will NOT use blue light blocking lenses when customizing your glasses.
