Firstly the Intellilens logo was neither on its glasses or the case. There no certificate of authenticity. The case was of normal built quality. The cleaning cloth is not microfiber but a normal one. Now reviewing the glasses the frame have a slick and stylish look but not at all durable. If you drop it accidentally, there is a fair chance it might break so you handle it with extra care. The lens is colourless and gives greenish, bluish and violet reflection so it definitely has uv coating but the cut down of uv light or blue light in particular is very minimal. I didnt feel that much relief when using it for prolonged period infront of the smartphone. Also the first time i tried on the lens, i felt a bad irritable headache. It also happened every successive time i tried so i had to remove the glasses time and again. Further the lens is not hydrophobic or Oleo phobic plus gets smudged easily if put fingers on it. You clean it every time. There were lot more cons than pros so i had to return the lens.
