Issues with the latest wave of 'smart glasses' seem to be piling up as some of the world's biggest tech companies prepare to sell millions in the coming years.

Women on beaches and outside shops are being approached by men, often wearing Meta’s Ray-Bans, who film them without consent. These secret recordings gain traction online before the women find out—and with little legal recourse. Mark Zuckerberg boasts that these glasses are 'some of the fastest-growing consumer electronics in history.'

Other major tech firms are also diving into this potentially lucrative market. Apple is reportedly developing its own version, while Google and Snap plan to release their own smart glasses.

The privacy concerns are obvious: small cameras, AI recording capabilities and unobtrusive design mean people can be recorded without knowing it. If predictions hold true, as many as 100 million people could buy a pair in the next few years, making public spaces harder to control.

David Kessler warns that 'there are some pretty dark places we could go here.' Meta's glasses, marketed under the tagline 'Designed for privacy, controlled by you,' often seem ignored as an increasingly popular use is recording pranks on unsuspecting people.
