Review on ALWAYSUV Computer Blocking Professer 1 25 by Sally Dickson

They are very light and semi-rigid. They block blue light (included with the blue light test kit). I've found that while studies say there's no real evidence of the benefits of blue light blocking, such as: B. improved sleep or eye health, but I can say that it helps with eye fatigue when working on the computer. What I like about these lenses is their optical transparency. correct zoom and no blurry areas on the edges like many other "cheaters". IMHO they are worth the price.
