What are you doing with your glasses? Use a microfibre cloth to clean them and there is no reason that they get scratched, and especially not every couple of years. I've had mine for 8 years and the only reason I've recently changed them is to get a different frame. Also, glass is really heavy, especially if you have to have them with a significant diopter, and it also prone to breaking if dropped onto a hard surface. Here in Germany you can still get regular glass if you so desire, so maybe it's just Israel.
