Review on 3-Pack Clip-On Blue Light Glasses: Blocks 98.5%, 78%, 50% Blue Light (420-460nm). Clear, Lightweight & Comfortable. Ideal for Laptop, Desktop, Phone & Gaming. Promotes Better Sleep, Fitness, Business & Health. by Peter Parks

Advantages: - Very nice appearance and quality - Light weight - Hard plastic protective covers for each set of clips. Percentage of light blocking. Cons: - The company name "Paleo Tech" is engraved/printed quite boldly in the top outer corner of the left lens on each set. It would be better if it was a smaller font or a responsive logo icon design instead of a name. Extremely reflective. Since I have anti-reflective prescription glasses, the reflections on the temples don't bother me when I look out from behind the temples. However, if you look at me, you will see a large reflection on the front of the clips. Hard plastic cases are very good, but I wish they were completely sealed so dust and dirt can't get in as easily. The lenses are secured in a small recess in the center of the body to prevent scratching or slipping. The recess is an open hole on the back. It would be better if they molded the plastic to have a flat sealed back with a recess molded/added inside.
