If you planned to use your Spectacles at nighttime, good luck. The camera doesn't perform well in low light.
Snap didn't release the specs of the glasses, so it's not clear the quality of the lens. But in trying them at different lighting levels, both inside and outside, I wasn't impressed with its abilities. Walking around New York City, it's never fully dark, so the glasses performed OK outside.
Recording indoors, however, was another story. That glasses could barely make out anything in front of me when I had two lights on, and once I turned the lights off and relied on window light, my video was just a black screen.
