Nash Computer Glasses by Felix Gray is a great wat to keep your focus on your work and ease on your eyes. We found ourselves many times during the day been in front of displays many hours. Moreover, Nash Computer Glasses has a blue light filter that decreases the amount of blue light displayed on the screen. Furthermore, the lenses also eliminate glare and have a high-quality frame. The size and measurements are 49-17-140 and create a perfect balance of productive and clear lens. The frame is handcrafted Italian acetate and comes in three colors: Artichoke, Black, and Whiskey Tortoise.
