I have a callus like lump from the nose piece on my glasses not fitting properly . I have had them before and when i got new glasses it pretty much would go away . The last it did not . That was 4 to 6 years ago . The new glasses sit just in front of it and press on it a little bit . My question is what is it and should i be concerned about it? It is not sore , never bleeds and it is soft, just bugs me . my father had the same thing for years . I am sixty one years old.
