Ordered three different glasses that promised to block blue light. They cost a little more than the other two, but I noticed a big difference right away! When I put them on I FEEL my eyes relax. The clarity of vision almost jumped off the screen. My eyes don't get tired after hours of screen time. It's a darker shade than the other two, sits more comfortably on my face, and is way ahead when it comes to blocking glare, avoiding eye strain, and improving screen clarity. It changes the way you look at colors as the lenses make everything yellow. I love that these reading glasses are so durable that I need them for my computer work. Other "blue light blocking" glasses can block blue light but do not improve vision.
