Are you as in love with ULTEM (or TR-90) as I am? In my humble opinion, this is the most exciting innovation in the way of frame manufacturing that I have experienced in some time! Frames made with ULTEM are lighter in weight, incredibly durable, and available in tons of colors! Better still, when you have a patient try on a frame made of ULTEM, they feel the difference, these things practically jump off my shelves! If you haven’t seen them, check them out, several companies are embracing the trend! Love it!!
