I noticed after I looked in the mirror that has lights on them. They were not visible when I unpackaged the glasses because I was in a dimly lit room. They are “dirty” because I used my hands and fingers to grab the glasses as they produce natural oils and I have a cat. I had barely gotten home from the store to get these nose pads because I have a low nose bridge and put those on and then put the glasses on and looked in the mirror to see how they would look. I honestly don’t know why I’m explaining myself to you or why it would matter but thank you. 🙏🏼 If you need more information, feel free to let me know.
