You don't see how this is misleading or fradulent (i.e. definition of a scam) in any way? A realistic image of someone wearing the glasses that don't exist yet, without disclosing it?
It's absolutely clear that if they're using AI generated images, they haven't even gotten a physical design of the product they're trying to sell.
So yeah, I don't think it's unwarranted to be skeptical when somebody shows an AI render and says "we'll ship this within 6 months".
