I was told if I would get rimless eyeglasses, I would want to have polycarbonated or high impact lenses. Which is recommended and what is the difference between these two lenses?

polycarbonated or high impact lenses. are just the same, these are 10 times more impact resistant than standard plastic lenses, the high index materials developed for eyeglasses is one material that has a number of very unique properties and also provides special benefits to eyeglass wearers.
