To date, Snap has sold about 150,000 pairs of Spectacles, CEO Evan Spiegel said at an industry event this week.

As reported by CNBC, Spiegel revealed the sales figure to Walter Isaacson during an on-stage interview at Vanity Fair’s New Establishment Summit, on Tuesday.

Spectacles can record 10-second video snippets, which are designed to approximate one’s natural field of vision. That's thanks to a 115-degree lens, which records circular video.

Stateside, online shoppers have been able to purchase Spectacles since February. Previously, Snap sold the glasses via vending machine. More recently, Snap began hawking the smart sunglasses online at Spectacles.com, while Amazon.com began carrying the fancy eyewear for $129.99.

For the privilege of owning a pair of the shades, Snap is charging European customers nearly $170 -- about $50 more than U.S. consumers.

To date, no company has been able to convince a critical mass of consumers to wear connected gadgets on their faces.

Google spent millions in development and marketing dollars before giving up on a consumer-facing version of Glass initiative. Yet Snap seems to have learned from Google's failure.

Spectacles’ price tag is far more reasonable than the $1,500 that Google charged for Glass. Snap’s glasses are also being sold as a single-purpose device, which is historically much easier to market.

Unlike Google, Snapchat enjoys a strong bond with young consumers -- the ideal demographic for starting trends and popularizing products.

Complicating Snap’s hardware strategy, Amazon is reportedly developing “smart glasses,” which will be directly connected to its Alexa virtual assistant.
