I purchased what i was told to be nikon seemax progressive eyeglass lenses with see coat max coating for 940$ (lenses only). however the store didnot indicate on my receipt what exactly i paid for and when i asked for the certificate of authenticity from nikon i was told that people normally donot ask for this and so that they threw this document away.i am not particularly happy with these lenses - they are rather thick, yellowish and smudge (dirty) very easily.i am looking for some halmark on the thenses that can pove they are the latest product available by nikon and i dont know what to look for.
>>> What are the identifying markings of nikon eyeglass lenses?
