Review on Stay Stylish and Protected with MERRY'S Fashion Blue Light Blocking Glasses - Men's Metal Frame Spring Hinge Readers for Eyeglasses by Savannah Williams

At first my thoughts were confused. I like the design at the moment but the lenses are a day old so let's see how long they last. What worries me is that I don't know how much blue light they block. This is my number one buying guide. I went online to see what blue blocking ability it had as I didn't see much of a difference in lens color on my average readers. My analysis is that it doesn't block much, if any, blue light. My analysis lacks rigorous analysis metrics, but I think I can make a fair judgment and say I'm not sure or have little faith in the blue light blocking ability of these glasses. If I'm wrong, I hope the manufacturer will correct me or direct me to a source to back up their blue blocking claim.
