Well in the description of these glasses they only block a percentage of blue light but not 100%. Knowing this and seeing that most other similar glasses in this price range do NOT block 100% blue light either. It is in order. I think they would be too dark if they did. These glasses are good. They fit well, not crooked. They are supplied in a nylon pouch within a black zipped protective sleeve. A small cleaning cloth is included. I am happy with these glasses as I have been using them for a while my eyes are not as strained or sore as before using these glasses. I use them at night on my fairly large tablet or on my Android phone. I can sit on this damn tablet for hours! I have an offer for a supplier/manufacturer. PLEASE include instructions for proper cleaning and handling of these glasses! There was nothing like that in the box. These types of lenses are coated with a film that blocks some of the blue light, so rough handling or cleaning with a solvent will scratch and/or cloud the film. I am happy with this purchase. I just deal with them a lot, more carefully than my normal readers.
