BlitzWolf BW-AG1: Affordable smart glasses offer heart rate and UV sensor, audio features, photochromic lenses

BlitzWolf has launched a new smart pair of glasses called the BW-AG1. This gadget doesn’t have a built-in display, which means these are not AR glasses, strictly speaking. That being said, a microphone and speakers are onboard, so voice assistants can be used without a connected smartphone. This feature is also offered by many headphones. Either way, the BW-AG1 retail for roughly $40.

Photochromic lenses available

Several model variants are available and come with different lenses. Depending on the version, these lenses are either clear or tinted. Aside from a classic pair of sunglasses, there is also a version with red and one with photochromic lenses. Simply put, the latter is an automatic pair of sunglasses whose lenses change their color in sunlight. That means users might not have to carry around an extra pair of sunglasses.

UV and heart rate sensor

Speaking of sun, the BW-AG1 also come with a UV sensor that is supposed to measure sun exposure. We cannot comment on the accuracy of these measurements, although such sensors are not particularly complex. The sun exposure is consequently displayed in the accompanying smartphone app and allows users to identify high UV radiation and take protective measures. Moreover, these smart glasses can optically measure heart rate and oxygen saturation.
