Everyone these days wears their sunglasses on their heads. After time the frames become stretched and they loose tension and start falling off your face.
Some frames will allow you to adjust them by heating up the bridge, this can only be done a couple of times and is limited by the flexibility of the plastic. Eventually the frame will become brittle and it can no longer be adjusted.
We offer a product that allow you to simply tighten the tension on your plastic frames and give you additional life out of those old glasses.
