Glasses cleaning help!

Le

So I was just prescribed glasses not too long ago and i just found them. They have stains that no matter how hard I try to wipe off they don’t want to come off. Someone please help I’m flipping out! Idk if my little sister touched them or if I cleaned them with the wrong solution previously. I need some advise on how to take these stains off. They look more like water stains, they are not white but mostly clear.
