dropped my small sun zy-t13

Now I need a lens. It survived the fall but putva flat ding on the edge of the bezel. I was able to pound the flattened edge out round and you can barely notice where it was dropped but now I noticed that the lens is chipped just under the bezzlle ring. Is the lens replaceable or is it pressed together and unserviceable?

4th picture down shows the lens.

I think I have replaced the lens…could it be a standard 55mm lens?
