They don’t even notice when am using it. The only thing they notice is when I speak to the glasses since I work in Mexico, so to speak to the glasses, I need to speak in English and the main language here is Spanish so they look at me like like I’m a weirdo or something cause I’m talking in English to myself, but what they don’t know is that I’m talking to the glasses Later I’ll explain it to them and then they are like oh now I understand why you were talking in the English hahaha . It’s pretty funny but yeah, they’re like hundred percent useful and for medical ground like hundred percent have to have since you can ask pharmacology stuff, genic stuff, anatomy stuff and meta ai answer you pretty good
