Felix Gray Hamilton Blue Light Blocking Glasses

To protect eyes from Blue Light, there are many different technologies out there that will filter Blue Light for you. However, not all Blue Light filtering technology is created equally. We’re walking you through 5 main ways to filter Blue Light and breaking down the pros and cons of each solution. The measurements for most pairs of glasses are located on the inside of the temple arm. There you’ll find listed in order the lens width, bridge width, and temple arm length (49-21-140mm) measured in millimeters. If you already have a pair of glasses that fit you well, we recommend comparing to those measurements. The lens width is a horizontal measurement and gives you a sense of how large the frames will be. This will help you pick a frame that isn’t too wide or too narrow for your face. You’ll want your eyes to align with the center of the frame.
