- There are two main ways these eyeglasses can protect against automatic recognition. The first one uses infrared lights. Infrared is a light beam visible to camera sensors but not the naked eye. When wearing glasses with embedded infrared in a photo op, software will be unable to use algorithms to recognize your face in the photo.
- The second pair uses retro-reflective materials on the glasses’ surface to return the flash directly back at the camera. This means the eyes will be surrounded by a halo of light that will also make it hard for computers to tag a face.
- However, this solution only works with flash photography or if there is a strong enough light source to reflect coming from the camera’s angle.
