I bought these glasses because I wanted the glasses to block the blue light from the screens I work with all day and these frames are really cute, love the marble design. But when I tested how well the lenses blocked blue light, one lens didn't block it at all, while the other blocked it about 80%. I bought another pair of blue light glasses from a different brand and the other glasses came with blue light and a blue light test card. I used them to test these glasses and I'm glad I did because I don't get any protection from them. To return.
