First, these glasses don't come with a pink hue lens as depicted, they are black in tone.  The images therefore are false advertising. Second, the flexible silicone is much too flexible. The frame is too loose and slides off our 5 year olds head. Properly designed frames require a degree of stiffness to assure stability, which these Chinese imports do not have. Sure, they may be cute to a limited degree, but for sake of wear and practical use, we grade them as a total fail. Returned at once and will buy locally to assure proper results.
