Why don’t Looktech ai glasses come with an engraved brand logo by default or as an extra option?

I was wondering, why don’t Looktech glasses come with the brand logo engraved by default or at least as an extra option? Personally, I wouldn’t mind wearing the brand name on my face if the project delivers on what it promises.

If I had to engrave something for the extra $10, I’ll probably go with the logo (probably only characters allowed...) and "LOOKTECH"...
