Snapchat has unveiled the third generation of its camera-enabled Spectacles, which allow users to capture images and video to post to the social media site.
The new Spectacles 3, costing £330, will go on sale in the autumn, Snapchat confirmed.
They feature a strong, lightweight steel frame with circular lenses and adjustable acetate tips, and come in two colours - Carbon (black) and Mineral (gold).
Users can tap a button on the frame to start recording up to 60 seconds of video (including audio), or press and hold to capture a still.
LED indicator lights notify people when recording, and users will see a light as well.
Spectacles 3 will wirelessly sync images and video gathered from the glasses to a user's phone, where a range of 3D effects in the Snapchat app will allow users to enhance their uploads.
Spectacles, the company's first hardware product, launched in 2016 but have had a mixed history as a consumer product.
Snapchat admitted in late 2017 that it had written off around 40 million dollars in relation to unsold stock of first-generation Spectacles.
Since then, the glasses have been redesigned and made water-resistant.
The new Spectacles 3 include two HD cameras which will enable depth to be captured in images.
They will also come with a leather charging case which can hold up to four charges, the firm said.
Snapchat also confirmed that the new Spectacles will be a "limited edition product", with far fewer being made than the first-generation glasses.
As of last April, Snapchat had sold more than 200,000 units of its original Spectacle.
This in itself is a tiny fraction of the 203 million people who open the Snapchat camera each day, and share 3.5 billion Snaps every day.
