They also offer standard poly carbonate lenses free. Anti scratch and anti glare come with the lenses. Any other treatment you can get is given in a list and their cost. We added the blue light coating to help reduce screen fatigue. They also have designer brands if thats something important to you. I let my kids pick if they wanted a second pair of glasses or sunglasses. The insurance covered most of the cost. On one child everything was covered. The second I think we were out of pocket twenty bucks.
