Apparently i was dumb enough not to throw my old lenses and i took both of them when i went to my hometown. Now i cant tell which ones are the new ones and which the old ones. The old ones are Filcon IV with UV blocker and the new ones are Enfilcon A so if you can point a difference between the appearance of those 2 i'd probably be able to tell which are the new ones
Added (1). by the way, the one pair looks more blue while the other one looks more transparent
