The original "glassholes" were early adopters of Google's smart glasses over a decade ago. They failed due to high costs, unattractive design, and unaddressed privacy concerns from wearing a camera on your face.

Meta is avoiding those mistakes. With cheaper versions starting at around £220 and tie-ups with Ray-Ban and Oakley, the glasses are affordable and stylish. Apple and Google are both developing new models, while AI enhances their practical use.

Privacy remains the best hope for repelling these devices. They are denounced as "pervert" glasses for their potential to photograph and identify people, notably young women. Meta has not yet enabled face recognition but likely will once broader acceptance is achieved.

Face recognition could help middle-aged people identify irregular acquaintances. The glasses also offer better directions than holding out a mobile phone. However, the ability to be covertly filmed remains a serious concern. Backlash is growing, with bans in Wetherspoons pubs, courts, clubs, cinemas, and many restaurants. Campaigners aim to set societal norms against the devices.
