Today, I took the pair that had lost both of the little plastic pieces that cushion one's nose. Somehow or another both screws had fallen out at nearly the same time. My optician is Pavan Optical uptown. On the way back from work, I stopped in and got two shiny new ones. When asked how I could be helped, I must have fallen into Apple Corp's pervasive marketing hype. For the life of me I couldn't think of what they were actually called.
I ordered two eye-pads. I found the plural noun rather surprising as it left my lips. It sounded shocking especially since I've so successfully avoided buying Apple products for so many years!
