Lost DIOPTRIC sunglasses - Mojstrana - Peričnik

I have lost my dioptric sunglasses (black, Tommy Hilfiger brand) on 17th August - on the way from Mojstrana to Slap Peričnik. They were placed in black protective case.

Please, does anyone found them? Any ideas who to contact (local rental/guide agencies).

They are made especially to my eyes - useless for anyone else.

Thank you a lot.
