I found these glasses TO be a total waste of money. As a result of using this product I found that they did not effectively block blue light and did not do anything to prevent eye strain. The glasses were flimsy and broke easily, leaving me with a useless product. The only pro is that they were relatively cheap, but with such poor quality, it's not even worth the low price .Save yourself the trouble and invest in a better pair of blue light blocking glasses..
