Meta has managed to lower the starting price of its upcoming smart glasses with a display to about $800, down from a more expensive price of over $1,000, by using the tried-and-true method of “accepting lower margins to boost demand,” Bloomberg reports.

The glasses, which include a small screen for apps and alerts on the right lens, are expected to debut in September and will have to prove people actually want them. CEO Mark Zuckerberg has said smart glasses are the “ideal form factor for AI” and are central to the company’s vision for “personal superintelligence.”
