This is the cheapest price we have seen on these camera-equipped smart glasses since Black Friday of last year.

The Headliner version of the Meta Ray-Ban Glasses are on sale from Amazon with a 20% discount. Here's your chance to get the smart glasses for a more affordable price.

Meta is doubling the glasses’ built-in battery with its Oakleys, promising they’ll last for eight hours with standard use, and 19 hours if they’re on standby. Meta adds that you can recharge them to 50% in just 20 minutes with their case, and said the charging case holds up to 48 hours of charge.
